Remove inclusion of missing file in lib

Commiting merge with Mario's repository

Replacing extern declaration with #include of apropriate header file

Adding some comments, and removing a check for a semantic error in code being compiled.

Fix bug with inline function call in POU programmed in IL

Add support for finding type of a constant enumerated value and managing conflict between same identifiers defined in different enumerated data types

Fix bug in declaring variable of enumerated type

Fix what I think is a bug (has not yet manifested itself).

Merging with Lauren't recent change.

Merging two previous commits.

Clean up some code.

Fix bug with array attribute in structure declaration

Add better comments, and change name of functions to clarify what they do.

Remove incorect debugging assertion.

Skip CONFIGURATION declarations in stage 3 for now, so semantic analysis does not stop when a configuration is encountered.

Fix bug when generating initial value for function return type when it is a complex type

Fix bug in debugging variable list compilation with structure and array disabling

Fix bug with TRUNC function and with type conversion functions called with constant as parameter

Allow use of ENO keyword in structured variable field selector.

Fixing REAL_TO_INT conversion (behaved like a trunc and not like a round)

fixing INSERT function: was inserting into incorrect position. (submitted by Manuele)

Fix bug when generating integer with leading zero (octal value for C compiler)

Allow [EOL] after a label in IL.

Fix bug when using an enumerated or subrange type to define a structure element

Fix bug when declaring data type directly derived from array type

Fix conversion of binary digits to hex, when generating code.

Fix missing '(' when declaring new simple derived data type.

Ignore underscores in decimal integer constants when determining size in bits...

When checking semantics of expressions, skip semantic checking of data type definitions
(not yet supported). If we don't skip, all subsequent POUs would not be checked.

Fixing algorithm that determines bit size of constants containing underscores.

Merging with Edouard's version

Fixing bug related to setting array variables with values coming from other variables
(e.g. X[0] := Y;)

Added __IEC_OUTPUT_FLAG, to mark variable whose forcing implies refresh on eache cycle.

Fix bug when debugging located variables of type memory (%M) for all variable classes

Merging with Edouard's changes

Fixing code generation of array indexes in Function Blocks.

Commiting merge with Laurent's recent dead code removal change.

Adding fflush capabilities. It is sometimes usefull when debuging the compiler...

Adding missing semicolons.

fixed build error with gcc 4.5.2

Merged with Edouard's modifications

Fix bug when debugging located variables of type memory (%M)

Removed dead code

Fixing implementation of CU, CD, and CUD in standard library.

Deleting dead code.

Merging changes.

Added tracking of order by which tokens are processed by lexical analyser.
This helps in correctly formating error messages when constructs begin in one file, and end in another.

Adding tracking of filename in which token is located.

Reverted semantic error message so that Beremiz can parse them and that user can double-click on error message to open related POU and select the faulty line.

Fixing error message incorrectly changed in previous merge.

fixing C code generation of return_statement_c and exit_statement_c

merging the Edouard's version.

fixing exit_statement_c: produce 'break' instead of 'exit(0); (Thanks to Manuele)

Fixing code generation of standard conversion functions.

Re-generated std lib related code, with updated headers, updated all forgotten headers

Merged matiec library headers update from Mario to LGPL

Changing to LGPL for library functions.

Updating origin and license info of library fuctions.
Conclude missing counter FBs.

Leave standard function names hardcoded, as these are considered keywords even though
they may not be implemented in the library.

New version of bistable.txt - due to license issues.

Make semantic error message compatible with beremiz

Merge

Fixes to make handling of standard functions in Semantic analyser compatible with code generation of standard functions

Merge with changes from Mario

Fixing stupid bug (that was disabling code generation).

Adding Makefile for Darwin (thanks go to Manuele)

starting to add proper header file with declaration of standard functions

Fixing error messages for IL semantic errors (brocken in a previous changeset/commit).

Updating license info (with Edouard's permission for relevant files).

Updating License info (with Edoaurd's permission for relevant files).

Adding some debug info

Do not crash when checking semantics of undeclared symbolic_variable.
NOTE: this update may have broken the printing of error messages
during semantic analysis of IL code.

Updating licensing information.

Error messages (stage3) now better identify the location of the error.

Adding debug conditional printf()s in stage 3.
Printing semantic error info to stderr instead of stdout.

Bug when function call result is a parameter of another function call fixed.

A forgotten case in type size getter switch prevented debugging outputs.
