mysqli + mysql functions (PHP5/MySQL 4.0)

When attempting to compile PHP 5.0.4 with MySQL 4.0, I received some strange errors from attempting to use --with-mysql and --with-mysqli. After getting it to configure correctly, where it finds mysql and mysqli support, when I run make I get these odd compile errors:

If I try and compile with 4.0, I get those errors for mysqli. If I try and compile with 4.1, I get those errors with mysql.

Ideally, i'd like this to work for 4.1 (having both mysql and mysqli functions). Any suggestions are appreciated.
