Hi,
It appears that TCC does not recognize C99 _Pragma keyword
and instead treats it as implicit function declaration or syntax error:
$ cat main.c ; ./tcc -std=c99 main.c ; ./tcc --version
int main(void) {
_Pragma("");
return 0;
}
_Pragma("");
main.c:2: warning: implicit declaration of function '_Pragma'
main.c:5: error: identifier expected
tcc version 0.9.28rc 2024-12-12 mob@ea75d5c (x86_64 Linux)
I haven't seen this anywhere reported.
The quick workaround is to wrap '_Pragma' with macro like so:
#if defined(__TINYC__) && !defined(_Pragma)
# define _Pragma(x)
#endif
