http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60498 --- Comment #8 from Jakub Jelinek jakub at gcc dot gnu.org --- Sure, but with -std=gnu++11 __STRICT_ANSI__ isn't defined (as intended).

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60498 --- Comment #9 from Jonathan Wakely redi at gcc dot gnu.org --- Definitely a Cygwin bug, their header should test: #if !defined(__STRICT_ANSI__) || (__STDC_VERSION__ = 199901L) || (__cplusplus = 201103L) That way the functions will be defined for any -std=gnuNN mode, for C99, and for C++11, which would be correct.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60498 --- Comment #10 from Jakub Jelinek jakub at gcc dot gnu.org --- Note, you've listed also plenty of non-standard functions like asiprintf, I guess those certainly shouldn't be available for __STRICT_ANSI__, even for -std=c99, -std=c11 or -std=c++11.
