The ftepp now always outputs into a string buffer, with -E the buffer will be dumped to stdout or the via -o specified file, without -E it'll be passed to the parser to be compiled 2012-11-18 12:33:53 +00:00			`GMQCC_DEFINE_FLAG(FTEPP)`

-fperl-logic, off by default, so casting to boolean now 2012-11-21 18:40:11 +00:00			`GMQCC_DEFINE_FLAG(PERL_LOGIC)`

introducing -fassign-function-types, previously guarded by std==qcc this is now the flag to cause a warning (-Wassign-function-types) instead of an error when assigning functions of wrong types 2012-11-25 22:27:48 +00:00			`GMQCC_DEFINE_FLAG(ASSIGN_FUNCTION_TYPES)`

## concatenation, -Wpreprocessor warning about redefining macros, #undef 2012-11-16 21:54:59 +00:00			`GMQCC_DEFINE_FLAG(PREPROCESSOR)`
Since like with parsing, the preprocessor state has to be preserved across files for macros, we do that now, and with that introduce a new warning: -Wmultifile-if in case an #if spans over several command-line-provided source files (or progs.src file provided for that matter) 2012-11-18 10:54:11 +00:00			`GMQCC_DEFINE_FLAG(MULTIFILE_IF)`
warn about double function declarations... 2012-11-23 21:22:22 +00:00			`GMQCC_DEFINE_FLAG(DOUBLE_DECLARATION)`
-Wconst-var 2012-11-25 14:56:13 +00:00			`GMQCC_DEFINE_FLAG(CONST_VAR)`
