But what if a recent glibc version isn't used?
Would GCC still be able to compile the following code?
int main (void)
{
#if __STDC_VERSION__ >= 201112L && ! __STDC_NO_THREADS__
_Thread_local int i = 17;
#endif
return 0;
}
Shouldn't GCC define __STDC_NO_THREADS__ to 1 by default and stdc-predef.h
undefine it if _Thread_local is supported at the library level?
