You could try doing the make to get the compile command on the screen, and then
pasting a copy of the command to the curent command line, replace the `-c' with
a `-E' and pipe the result to ``less''.

To do this you will have to go into the gnome directory and type ``make gscreen.o''
The altered command will look something like:

gcc -E -I..  -I./.. -I../slang  -I./../vfs -I./../slang -I.. -DBINDIR=\""/usr/local/gnome/bin/"\"
-DLIBDIR=\""/usr/local/gnome/lib/mc/"\" -DICONDIR=\""/usr/local/gnome/share/pixmaps/mc/"\" 
-DLOCALEDIR=\""/usr/local/gnome/share/locale/"\" -DCONFDIR=\""/usr/local/gnome/etc/"\"
-DDESKTOP_INIT_DIR=\""/usr/local/gnome/lib/mc/desktop-scripts/"\" -I./../vfs -DHAVE_X -DHAVE_GNOME
-I/usr/local/gnome/include -DNEED_GNOMESUPPORT_H -I/usr/local/gnome/lib/gnome-libs/include
-I/usr/local/lib/glib/include -I/usr/local/include -I/usr/X11R6/include  -DHAVE_CONFIG_H -g -g
-I/usr/local/lib/glib/include -I/usr/local/include  -I/usr/X11R6/include -I. -I./../src gscreen.c |
less

This runs only the C preprocessor and outputs the result to the pager ``less''.

search the output for the MAX definition, or if not found, a reference to glib.h.
you should get an idea from that.
