Something not unlike:
AC_ARG_WITH(--with-pciids-path, AS_HELP_STRING(...), [PCIIDS_PATH=$withval], [PCIIDS_PATH=/arbitrary/default])
AC_DEFINE_DIR(PCIIDS_PATH, PCIIDS_PATH, [Path to pci.ids])

Where AC_DEFINE_DIR is available from:
http://autoconf-archive.cryp.to/ac_define_dir.html

And PCIIDS_PATH will now be available as a preprocessor define.

Cheers,
Daniel
