Description:
------------
When compiling a C program that makes use of the embedded SAPI (embed.h), there are a few compile warnings that would be nice if they could be fixed :) Also, this is a manually compiled version of PHP, not emerged from Gentoo's portage.

Reproduce code:
---------------
Compiled using the following:
gcc -I/usr/lib/php5/include/php/ 
    -I/usr/lib/php5/include/php/main
    -I/usr/lib/php5/include/php/Zend
    -I/usr/lib/php5/include/php/TSRM
    -I/usr/lib/php5/include/php/sapi/embed
    -L/home/crisp/php/local/lib
    -Wall -Wextra -lpthread -ggdb -o httpd *.c /home/crisp/php/local/lib/libphp5.so

The code itself is here:
http://crispycrisp.org/test.txt

Expected result:
----------------
No compile warnings

Actual result:
--------------

These warnings happen only when the embed lib is build with --enable-
debug. I fixed most in CVS. The rest are harmless anyway and only needed 
for debugging.
