Have php 4.2.1 already installed and was going to installing the release canidate on top of it.

>./configure --with-mysql --with-apxs=/usr/local/apache/bin/apxs --with-mm

>make

I get these errors at the end of the make:

/usr/bin/ld: Dwarf Error: Invalid or unhandled FORM value: 14.
/usr/bin/ld: Dwarf Error: Invalid or unhandled FORM value: 14.
ext/mysql/libmysql/my_tempnam.lo: In function `my_tempnam':
/home/http/builds/php-4.3.0RC1/ext/mysql/libmysql/my_tempnam.c:103: the use of `tempnam' is dangerous, better use `mkstemp'

I saw that the tempnam error is not getting fixed but did not see anyone else report the Dwarf Error.
