-D_REENTRANT

[Sven Neumann <sven gimp org>]

Hi,

I noticed that only glib and atk are compiled with -D_REENTRANT. Pango
and GTK+ lack this compiler flag and thus do the wrong thing in 
threaded environments. This doesn't seem to be a problem with glibc
which redefines some symbols if an application is linked against 
libpthread but it leads to strange errors with libc implementations
that don't have this behaviour.

I'd suggest a change like this one for Pango:

I can come up with a similar patch for GTK+ if you agree that this
is the right thing to do.


Salut, Sven
