Please note that those macros are defined by gcc only when _GNU_SOURCE is supplied. With tcc they are unconditionally defined except on Windows (which does not use glibc at all). C.

Hi Christian, It seems consistent to me. Regards. Le 16/01/2020 à 06:55, Christian Jullien a écrit : Hi all, When we use tcc on Linux, we also use /usr/include/*.h. Some definitions are only visible for C11 and controlled by use of _ISOC11_SOURCE as used by glibc (see for example http://man7.org/linux/man-pages/man7/feature_test_macros.7.html). As tcc is C99 by default, I propose to also automatically set _ISOC99_SOURCE by default but _ISOC11_SOURCE when -std=c11 is used. Wdyt? Reference: _ISOC99_SOURCE (since glibc 2.1.3) Exposes declarations consistent with the ISO C99 standard. Earlier glibc 2.1.x versions recognized an equivalent macro named _ISOC9X_SOURCE (because the C99 standard had not then been finalized). Although the use of this macro is obsolete, glibc continues to recognize it for backward compatibility. Defining _ISOC99_SOURCE also exposes ISO C (1990) Amendment 1 ("C95") definitions. (The primary change in C95 was support for international character sets.) Invoking the C compiler with the option -std=c99 produces the same effects as defining this macro. _ISOC11_SOURCE (since glibc 2.16) Exposes declarations consistent with the ISO C11 standard. Defining this macro also enables C99 and C95 features (like _ISOC99_SOURCE). Invoking the C compiler with the option -std=c11 produces the same effects as defining this macro. _______________________________________________ Tinycc-devel mailing list Tinycc-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/tinycc-devel -- -- i...@sibian.fr -- Développeur compulsif
