use
AH_BOTTOM([#include <custom.h>])
and place your corrections to custom.h. It is "bottom", so you have all
the tesults of autoconf checks at your hand.
gawk-3.1.5.tar.bz2 can serve as an example of this technique.

It's easy to get rid of it:
AC_CONFIG_COMMANDS_PRE([DEFS=])
Bot you could break some things which rely on this define:
1) gnulib -- most of gnulib modules rely on HAVE_CONFIG_H
2) ansi2knr.c -- if you are using the ansi2knr option of Automake.
In theory, small projects need not use config.h; DEFS would then become a
list of all defines, -DHAVE_STRING_H=1 -DVERSION=1.0.0 etc.
gnulib and ansi2knr.c still try to be compatible with this.
Have a nice day,
