PHP was configured with the following string:

  ./configure
    --with-apache=/usr/local/src/apache_1.3.11
    --disable-debug
    --enable-track-vars
    --with-informix=/usr/informix

However, the config_vars.mk file contains references to mysql libraries.  The build fails immediately upon entering ext/mysql -- due to the fact that mysql is not installed on this machine (and won't be).

Removing all references to mysql from the config_vars.mk file allows PHP to compile, but once the following Apache build hits src/modules I get the following errors:

I haven't tracked down the source of all of the errors, but I was a little concerned to see mysql_module_entry showing up there as well.  I had to do some manual work in the PHP 4b3 build to correct the alloca issues, so I'll work through the whole stack and report back.  This may or may not be a partially related issue.

Of these, I would consider the mysql assumptions in the initial PHP4 build by far the most troubling.
