I have mysql-3.22.32 and apache_1.3.12 and both installed without problems.
My gcc is gcc version 2.7.2.1.  I have tried to upgrade to a newer version of gcc
but, without success.

I ran configure with the following parameters:
[ 529 hunk->php-4.0.0 >./configure --with-mysql=/usr/local/mysql --with-xml\
 --with-apache=../apache_1.3.12 --enable-track-vars\
--with-gnu-ld

There are no errors with the configure script.  When I run make I get the following errors
[ 529 hunk->php-4.0.0 > make
"Makefile", line 39: Need an operator
"Makefile", line 40: Need an operator
"Makefile", line 41: Need an operator
Fatal errors encountered -- cannot continue

Here are the appropriate lines from Makefile
include $(top_srcdir)/build/rules.mk
include $(top_srcdir)/build/library.mk
include $(top_srcdir)/build/program.mk

I have tried placing = between 'include' and '$'  and then it fails on the next line.
        @$(LIBTOOL) --silent --mode=install cp libphp4.la $(phptempdir) /libphp4.la >/dev/null 2>&1
The error is 
[ 531 hunk->php-4.0.0 > make
--silent: not found
*** Error code 1
Stop.

If someone could share some light on this I would be very grateful.
