getpwuid_r again (problem if compiling -static)

[Damon Chaplin <damon karuna freeserve co uk>]

If I compile an app with -static I get the warning:

GLib-WARNING **: getpwuid_r(): failed due to: No such user 1000.

I think this is another glibc bug - it returns the wrong error code
when there is insufficient space.

Anyone else get it?
