Hi there, 
While compiling PHP on my Mac OSX box I came accross the 
following problem:

The file:
/php-4.0.5/main/internal_functions.c

There is a block of code that looks like this:

#include "ext/mysql/php_mysql.h"n#include 
"ext/pcre/php_pcre.h"n#include 
"ext/posix/php_posix.h"n#include 
"ext/session/mod_mm.h"n#include 
"ext/session/php_session.h"n#include 
"ext/standard/php_standard.h"n#include "ext/xml/php_xml.h"

What it looks like has happened is that when this include 
file was generated there was supposed to be a '\n' between 
the #includes in the C code but only a 'n' was inserted, 
for now I fixed this manually, I don't know if this is OS 
specific, Just thought I would drop you a mail to let you 
know :O)

Regards
