D:\wxWidgets-2.9.5.vadz.2\include/wx/string.h:182:31: error: 'strcasecmp' was not declared in this scope

With compile option '-std=c++11' mingw32 defines __STRICT_ANSI__. With that there is no 'strcasecmp' available for implementing 'Stricmp'.

  • Status changed from new to confirmed

Actually I have really no idea why do we repeat all these tests here when we already have wxCRT_StricmpA() defined in wx/wxcrtbase.h. I'll just change the code to use it instead.

  • Resolution set to fixed
  • Status changed from confirmed to closed

(In [74571]) Just forward Stricmp() in wx/string.h to wxCRT_StricmpA().

Don't redo the tests already done in wx/wxcrtbase.h in wx/string.h too,
especially as they were not done correctly there (they didn't take into
account the case of MinGW in strict ANSI mode). Just call wxCRT_StricmpA().

This also allows us to get rid of HAVE_STRCASECMP_IN_STRING[S]_H tests in

Closes #15349.
