I have this working, but I'm not certain if I've done it the best way.

Here's what I did:

- added this to configure.in:

    AC_PATH_PROG(GDB, gdb)

- added this to coregrind/Makefile.am:

    vg_main.o: CFLAGS += -DWHERE_IS_GDB=@GDB@

- changed coregrind/vg_main.c to use WHERE_IS_GDB for the path.

This works, but it would be better if the GDB variable was put into a .h
file, so it's available everywhere -- that's better than having to feed it
in to every file that needs it with -D.  This could be done by introducing
eg. vg_skin.h.in, but that would be a pain, especially just for one
variable.

I tried various ways to get the WHERE_IS_GDB variable put into config.h,
but didn't manage... this would be a better solution.  Does anyone know
how to do this?

Thanks very much.
