This file must be translated to C and modified to build everywhere.
Run flex like this:
flex -i --prefix=cmDependsFortran_yy --header-file=cmDependsFortranLexer.h -ocmDependsFortranLexer.cxx cmDependsFortranLexer.in.l
Modify cmDependsFortranLexer.cxx:
- remove TABs
- remove "yyscanner" argument from these methods:
yy_fatal_error, cmDependsFortran_yyalloc, cmDependsFortran_yyrealloc, cmDependsFortran_yyfree
- remove all YY_BREAK lines occurring right after return statements
- change while ( 1 ) to for(;;)
Modify cmDependsFortranLexer.h:
- remove TABs
- remove the yy_init_globals function
- remove the block that includes unistd.h
- remove #line directives (avoids bogus warning on old Sun)
