Wed, 10 Dec 2014 12:06:45 +0000 mjsousa Delete un-used declaration.
Wed, 10 Dec 2014 11:57:43 +0000 mjsousa merge

Sat, 29 Nov 2014 13:43:20 +0000 mjsousa Add a pre-parsing phase to stage1_2 (allows source code that references POUs and datatypes before they are declared)

Sat, 25 Oct 2014 11:21:40 +0100 mjsousa Filling of symbol->scope annotation moved from narrow to fill_candidate_datatypes_c (became possible because narrowing of struct, array and symbolic variables is now done directly in fill_candidate_datatypes_c)
Sat, 25 Oct 2014 11:15:55 +0100 mjsousa fill_candidate_datatypes_c now uses search_varinstance_decl_c instead of search_varfb_instance_type_c (moving towards deprecation of search_varfb_instance_type_c)

Fri, 08 Aug 2014 10:26:52 +0100 mjsousa Introduce absyntax class for keyword ANY, and use REF_TO(ANY) as datatype of NULL literal.
Wed, 06 Aug 2014 10:43:15 +0100 mjsousa Fix bug (introduced a few commits ago) when generating SFC actions that are mapped onto variables --> Make generate_sfcdecl_c stateless (i.e. does not depend on order by which it is called).
Thu, 31 Jul 2014 17:49:44 +0100 mjsousa Add support for the 'NULL' keyword, defined in version 3 of IEC 61131-3.
Tue, 29 Jul 2014 13:39:40 +0100 mjsousa for option '-Op' (generate <pouname>.h/c): add '#include <pouname>.h' to the .c file, and '#ifdef <pouname>_H' to the .h file
