I think you got the wrong PR here: your doc patch is about PR
preprocessor/41540, not 41590, which AFAICT is unrelated.

Which version of GCC are you using?



$ cat head.h

#define HEAD 1



$ cat stdc0.c 

#include head.h

#define STDC0



$ gcc -I. -g3 -save-temps -c stdc0.c 

$ grep __STDC__ stdc0.i 

#define __STDC__ 1



$ gcc -v

Using built-in specs.

gcc version 4.7.2 20121109 (Red Hat 4.7.2-8) (GCC) 



The above also works with gcc version 4.9.0 20130507 (experimental) (GCC).

This even affects current mainline.

As the PR summary states, this only affects STDC_0_IN_SYSTEM_HEADERS

targets:



ro@apoc 54  grep -r STDC_0_IN_SYSTEM_HEADERS gcc/config

gcc/config/sol2.h:#define STDC_0_IN_SYSTEM_HEADERS 1

gcc/config/sparc/netbsd-elf.h:#undef STDC_0_IN_SYSTEM_HEADERS



I've just verified it again on i386-pc-solaris2.11.
