Does this happen with latest CVS snapshot from http://snaps.php.net/ ?

yep :

/bin/sh /usr/src/php4-200110231200/libtool --silent --mode=compile gcc  -I. -I/usr/src/php4-200110231200/ext/sockets -I/usr/src/php4-200110231200/main -I/usr/src/php4-200110231200 -I/usr/include/apache -I/usr/src/php4-200110231200/Zend -I/usr/src/php4-200110231200/ext/xml/expat  -DCOBALT_RAQ_LED -DLINUX=2 -I/usr/src/php4-200110231200/TSRM -g -O2 -prefer-pic  -c sockets.c

Ok, I probably don't have to ask if it works about current CVS or RC. SO_SNDLOWAT and friends are still in ext/socket.

Anyway, cany ou grep your system header files if the constants SO_SNDLOWAT , SO_RCVLOWAT , SO_SNDTIMEO and SO_RCVTIMEO are defined somewhere?

The 'should' be in /usr/include/asm/socket.h, the linux kernel defines them in

include/asm-i386/socket.h:#define SO_SNDLOWAT   19
include/asm-mips/socket.h:#define SO_SNDLOWAT   0x1003

Maybe it's a problem with your header files?

If you find anything, please also try latest RC

Feedback.

well, maybe its because im using an older kernel...
 2.0.34C52_SK

the constants were not found in socket.h, but heres a dump of what is :

i dont think trying the lastes RC would help seeing as i dont think those constants are defined anywhere, would you be able to define them for yourself if they are not already defined?

ill try the lastest RC anyway, for the sake of completeness... 

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
