I'm playing with CRT compiled with -Os -flto -ffat-lto-objects flags and
for some unknown reasons I'm getting following warning when compiling
trivial wprintf hello world application with msvcrt.dll and with mingw
wprintf function (-D__USE_MINGW_ANSI_STDIO=1).
mingw-w64-headers/crt/wchar.h:1426:18: warning: type of ‘mbrtowc’ does not
match original declaration [-Wlto-type-mismatch]
size_t __cdecl mbrtowc(wchar_t * __restrict__ _DstCh,const char *
__restrict__ _SrcCh,size_t _SizeInBytes,mbstate_t * __restrict__ _State);
^
misc/mbrtowc.c:96:1: note: ‘mbrtowc’ was previously declared here
misc/mbrtowc.c:96:1: note: code may be misoptimized unless -fno-strict-aliasing
is used
I thought that adding missing __cdecl would fix it, but no. Warning is
still there. So I sent at least the patch to align declaration.
Do do you have any idea, why GCC is throwing that warning? Why the
declaration for LTO does not match?
Btw list mingw-w64-public@lists.sourceforge.net stopped working, it
rejected all my emails from the last week with following error:
Remote-MTA: dns; mx.sourceforge.net. (216.105.38.6, the server for the domain
lists.sourceforge.net.)
Diagnostic-Code: smtp; 451 Could not complete recipient verify callout
Seems that your email was rejected too, it is not in archive at:
