Ensure `wint_t' is defined before use in include/stdio.h
While trying to get nptl/tst-initializers1.c to include the test skeleton, I came across a couple of speed bumps. Firstly: after making the appropriate changes to the test, running `make check' led to this error: > In file included from ../malloc/malloc.h:24:0, .. > from tst-initializers1.c:60: > ../include/stdio.h:111:1: error: unknown type name `wint_t' > extern wint_t __getwc_unlocked (FILE *__fp); So, `wint_t' is used before being defined. Question: Why did test-skeleton.c not cause this error in any of the other tests that include it? Anyway, I noticed include/stdio.h includes stddef.h, which in turn defines `wint_t', but only if `__need_wint_t' is defined. So I put in a `#define __need_wint_t' before the include to get rid of the error. Is that the correct fix? A subsequent `make && make check' led to this second error: > from tst-initializers1-c89.c:1: > ../test-skeleton.c: In function `main': > ../test-skeleton.c:356:11: error: `for' loop initial declarations are only > allowed in C99 mode > for (struct temp_name_list *n = temp_name_list; Although there seem to be several other C89 no-noes in test-skeleton.c, I needed only to fix this specific one for gcc-4.8.3 to stop complaining.
