Subject: C99 ctype function: isblank [PATCH]
Message-Id: <E181y1U-0000V7-00@phekda.freeserve.co.uk>
Reply-To: djgpp-workers AT delorie DOT com

Hello.

Please find below a patch to add the isblank function from
the C99 standard. Here's a simple test program:

---Start test program---
#include <ctype.h>
#include <stdlib.h>
#include <assert.h>

int
main (void)
{
  assert(isblank(' '));
  assert(isblank('\t'));
  assert(!isblank('a'));

  return(EXIT_SUCCESS);
}
---End test program---

OK to commit?

Bye, Rich =]
