The configure script still treats X11 as an atomic package. This could
cause problems on platforms which have started using modular X11

I don't know whether newer versions of autoconf include tests for
individual X11 components, but autoconf 2.13 doesn't, and I wouldn't
want to force an upgrade over this issue alone.

It should be safe to check for X11 libraries and headers like any
other, provided that the relevant compiler/linker switches are used.
For header checks, $X_CFLAGS needs to be added, while library checks
need to use:


See the checks for Motif, OpenGL and Tk for examples.

BTW, it's actually Togl which uses Xmu (XmuLookupStandardColormap).
