Does anyone know what I should expect, or where I should look to find
out, please ?
Glibc provides it in the /usr/include/stdc-predef.h file which is
implicitly pre-included by GCC.
Ah ha ! Thank you.
I guess that accounts for the "predefined" _STDC_PREDEF_H.
AFAICS, the decision to "preinclude" <stdc-predef.h> is made when gcc is
built, depending on the target. Deep Magic of the First Magnitude.
Thanks,
