Re: [gentoo-embedded] uClibc and PHP

I got php-cgi running using this patch:

I don't know if this works as a patch as I have just edited the files by 
hand.
I found it at the uclibc mailing-lists:
http://www.uclibc.org/lists/uclibc/2004-December/010664.html
Which gave me a working php-cgi-4.4.0 on a uclibc-mips. I haven't 
submitted this to bugs.gentoo.org because I have tweaked alot more by 
hand and I wasn't sure this was the only patch needed.
This patch solved my __dn_skipname problems but I alsa disabled some 
more xml-stuff for all the localisation stuff unsupported by uclibc.
