>Description:
C99 standardised the isblank() macro/function which is currently protected by
the __BSD_VISIBLE macro and thus fails to be visible in a strict C99/SUSv3
compilation environment.
>How-To-Repeat:
$ cat isblank.c
#include <ctype.h>
int main(void) { return isblank('a'); }
$ c99 -D_C99_SOURCE isblank.c
isblank.c: In function `main':
isblank.c:2: warning: implicit declaration of function `isblank'
$ c99 -D_POSIX_C_SOURCE=200112L isblank.c
isblank.c: In function `main':
isblank.c:2: warning: implicit declaration of function `isblank'
