Clean up code (remove parsing of integers in stage 4).

Fix literal MACRO gcc compliant.

Add 'dimension' parameter to subrange_c, fill it correctly, and use it.

extract_int64() must not handle negation operation (was doing it incorrectly for INT64_MIN!)

Add support for -INT64_MIN values in literals.

Make compiler portable (do not assume int64_t is long long int)

Add missing set overflow flag.

Fix extract_integer_value.
Now we handle signed and unsigned in different mode.
(Thanks to Andreas)

Fix typo (thanks Manuele)

Remove potential access to NULL pointer.

fix error message.

Fix array index bound check to consider uint64 indexes/limits.

Fix structure initialize.

Add check array out of bound.

Code for debugging const_value annotations in abstract syntax tree.

Fix 'overflow' detection for real64.

small bug fix.

Fix compare expression in constat folding class.

Fix extract_real (thanks Manuele), and add check for overflow.

cleaning up the code...

Fix remaining overflow checks.

remove incorrect include file.

Correctly implement MOD operation and overflow checks (still missing uint * / MOD).

Re-insert errno=0 before calling strtoXX() (thanks go to Manuele)

cosmetic changes.

Add data structure for storing overflow of constant values.

make the compiler platform independent (i.e. no longer assume sizeof(double)==8).

create extract_real_value() in absyntax_utils. NOTE: overflows not yet handled!

Update constant folding: fixing minor bug.

Fix a few bugs of previous commit.

Start constant_folding class.

little typo in last commited code
add if(is_bool_type(sym)) this->bool_type->accept(*this) in generate_c_il_c::visit(il_default_variable_c*)
to get .BOOLvar instead of .FALSEvar resp. .TRUEvar ..

Change return data type of array_dimension_iterator_c.next()

Fix SFC stage4 error.

Renamed class, remove unused code, delete allocated objects.

Start sematinc range check class.

Located variables may have other data types besides ANY_BIT.

Add verify_is_lvalue to control_variable in for_statement.

Remove useless code, and replace with assertion.

Fix bug: initialise un-initialised variable.

Delete incorrect comment.

Add some comments...

Add high level comments.

Fix comment.

Fix the previous commit: check for errors in expressions used as subscripts.

Fix data type check array subscript field.

Merge changes.

Fix parsing os TIME literals & rename the extract_integer() function.

Fix generation of output for iec2iec.

Do not compile deleted files...

Do not compile deleted files...

ReDelete files - used in old method of supporting standard functions.

Remove file (used for old method of supporting standard functions).

Add TODO list!

Delete unecessary variable.

Fix __dt_to_timespec primitive function.
Set tm_isdst = 0 to disable DayLight Savig Time.
