Subject: [PATCH] mkostemp, mkostemps: Fix compilation error in C++ mode on Mac
 OS X.

Attempting to use the mkostemp module in gdb caused a build failure
when using the C++ namespace feature, because mkostemp was not
declared.  On OS X, mkostemp is declared in unistd.h, so this patch
extends the existing special case in stdlib.in.h to cover mkostemp and
mkostemps.

* lib/stdlib.in.h: Include <unistd.h> for mkostemp and mkostemps
on OS X.
