GTK+ 1.2.7: failing to compile gtkmain.c

["Frederic L. W. Meunier" <fredlwm marseille nitnet com br>]

Hi. I compiled succesfully GLib/GTK+ 1.2.6 and didn't changed
anything on the machine. I compiled GLib 1.2.7 using objdir
(compiling from another directory), and tried the same for
GTK+, configured with --with-xinput=xfree --disable-nls
--disable-glibtest. The error:

/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H

What's wrong? I don't see any error message. After this I have
-rw-rw-r-- 1 fredlwm fredlwm 111000 Feb 17 07:13 gtkmain.lo in
/usr/local/src/gtk+-1.2.7/objdir/gtk/.libs, but of course no
/usr/local/src/gtk+-1.2.7/objdir/gtk/gtkmain.o
