So, here I am again.

PART ONE.
Let me quote this first:
(this is from ./configure of glib, we're not speaking about gtk+ yet because
gtk+ requires a correctly-built glib to compile at all!)

configure: warning: the 'g_get_(user_name|real_name|home_dir|tmp_dir)'
                functions will not be MT-safe during their first call
because
                there is no working 'getpwuid_r' on your system.
configure: warning: the 'g_date_set_time' function will not be MT-safe
                because there is no 'localtime_r' on your system.


PART TWO.
This is my error output when I try to build the gthread source tree,
ignoring the warning above (only this one interests me at the moment,
because this is the only one that outputs errors)

In file included from gthread.c:42:

make: *** [gthread.lo] Error 1

Since it was complaining about pthread_cond_t, I looked around where this
definition could be found: eventually i found it in Xthreads.h!
So I copied Xthreads.h to the current directory manually and added

#include "Xthreads.h"

line to gthread-posix.c.

Unfortunately, it doesn't work yet.
And it's obvious: it must have something to do with MT thread safeness.
