Adding the #include satisfied the compiler, whatever the case.
Apparently glib-2-2.6.3 also includes G_GNU_NULL_TERMINATED?

At the advice of another respondant, I did:

[wtallman ansible c_stuff]$ pkg-config --modversion gtk+-2.0
[wtallman ansible c_stuff]$ pkg-config --modversion glib-2.0

The Slackware package is gtk-2-2.4.3-i486-1.  This implies a discrepency
in minor version numbers.

Now, a major problem seems to be pango.  Thus:

[wtallman ansible c_stuff]$ pkg-config --modversion pango

may or may not be the right version for the rest of the libraries.

I intend to get the gtk+ source for 2.6.3 and see if it matches the
Slackware package.  I presume that installing 2.6.3 (in /usr/local) will
tell me if it is satisfied with the pango version.

Any other suggestions?

Thanks, Yeti.
