<pre>Since the switch to default to C11, compliant program fails to build **by
default** (without forcing another mode) on windows:
#if defined(__STDC_VERSION__) && \
(__STDC_VERSION__ >= 201102L) && \
!defined(__STDC_NO_THREADS__)
# include <threads.h>
#endif
[ build with only "clang.exe -c test.c" ]
It is probably the same for other predefined macros.
This may be a library issue, but is it ok to default to C11 if there is known
library issue for such support?</pre>
