--- Comment #2 from Erik van Pienbroek erik-fedora@vanpienbroek.nl --- The mentioned testcase gives the expect result and doesn't show any warnings on the mingw-w64 toolchain which is currently in rawhide. Closing bug

--- Comment #3 from Christophe Fergeau cfergeau@redhat.com --- I'm still hitting this in f20 with mingw64-gcc, but this seems related to ccache:
$ which x86_64-redhat-linux-gcc /usr/lib64/ccache/x86_64-redhat-linux-gcc
$ LC_ALL=C x86_64-redhat-linux-gcc -Wimplicit-function-declaration ./mingw.c ./mingw.c: In function 'main': ./mingw.c:6:5: warning: implicit declaration of function '_ftime_s' [-Wimplicit-function-declaration] _ftime_s(NULL); ^ /tmp/ccswArMH.o: In function `main': mingw.c:(.text+0x1a): undefined reference to `_ftime_s' collect2: error: ld returned 1 exit status
$ /usr/bin/x86_64-w64-mingw32-gcc -Wimplicit-function-declaration ./mingw.c $ echo $? 0
No clue whether this should be reopened or not.

--- Comment #4 from Erik van Pienbroek erik-fedora@vanpienbroek.nl --- The symbol _ftime_s is win32 specific and part of the 'secure api': http://msdn.microsoft.com/en-us/library/95e68951.aspx Therefore it is expected that the symbol can't be found when using the native Linux gcc

--- Comment #5 from Christophe Fergeau cfergeau@redhat.com --- Sorry, dunno what I was thinking, I did not pay attention to the 'linux' bit in x86_64-redhat-linux-gcc and assumed this was a mingw one /o, apologies for the noise.
