That would probably work, but I'm kind of hesitant to create an empty
input file in cvs just to serve this marginal feature. (It wouldn't take
/dev/null because it tries to use .//dev/null.) Moreover, the likely
candidate name stamp-h.in is sort of reserved for doing the same trickery
on autoheader, in case we ever use that.

I came up with this:

diff -c -r1.86 configure.in
*** configure.in 2001/01/01 23:10:09 1.86
--- configure.in 2001/01/02 19:20:16
***************
*** 1140,1144 ****
],
[
# Update timestamp for config.h (see Makefile.global)
! echo >src/include/stamp-h
])
--- 1140,1144 ----
],
[
# Update timestamp for config.h (see Makefile.global)
! test x"$CONFIG_HEADERS" != x"" && echo >src/include/stamp-h
])

This only updates the stamp file if config.h is actually being considered
by config.status.
