HI, Eric, thanks for the reply. I tried your suggestion. I have two issues: 1. "configure" failes its tests of C compilation on the shell since it tries to use my shell scripts. I tried to comment out "AC_PROG_CC" and it didn't seem to disable the check after "autoreconf". 2. i also need to inherit the options on the compile line like file name and CFLAGS. Can I do that with your suggestion? Thanks again.

Which autoconf rule should I change or redefine? Or maybe this is an automake problem? I'm new to this. Any help is appreciated. I would write a script that does the preprocessing and calls mytool, put that on my path, then invoke ./configure CC=myscript. - -- Life is short - so eat dessert first!
