buildconf problem; ext_skel patch

For some reason I can't post to this list from sam@ananova.com, nor can I post to php-dev-help or php-dev-owner I am writing my first php extension (!) to interface to the Muscat libraries; When I run ./buildconf I get: rebuilding Makefile templates rebuilding configure autoconf: Undefined macros: ***BUG in Autoconf--please report*** AC_ADD_INCLUDE ***BUG in Autoconf--please report*** AC_PROVIDE_ nawk: input record ` EXTRA_LDFLAGS="-...' too long input record number 41573, file /tmp/acout.28455 source line number 3 I managed to make this happen WITHOUT my new empty extension by merely touching the config.m4 file of the mysql extension. I am running on solaris 2.7 with autoconf 2.13, and the latest non- cvs php4 download I note there are various acinclude.m4 files, and the top level acinclude.m4 defines this macro. But neither I (nor it seems at least the mysql maintainers) have built into their extensions what is required to include these files at the start. So.... beg beg, how do I do it? I also enclose a patch to ext_skel which has missing quotes around "$nohelp" in two cases which stop it working on solaris /bin/sh SAm
