Compiling Trouble of libevent

Hi there, i probably sent you all a subscribe mail, sorry for that. I have some trouble compiling the beta extension for libevent. http://codepad.org/RdVLgfdd The compile breaks first at tmp/pear/temp/libevent/libevent.c: In function ###f_event_set### /tmp/pear/temp/libevent/libevent.c:631: error: expected expression before ###p_stream### wich seems to be a call to a zend-function. Ive tried the "pecl install ..." with different versions of gcc 4.3.2 now and php 5.3.3-7 (5.2.9 before) with Suhosin Patch, Zend Engine 2.3.0, libevent 1.4.13 (1.3e-3 before, 2.0.10 (libevent2)before). Running Debian Pinning (stable/testing(/unstable)). It always stops right at this position. Am i missing packages? i even tried installing (compiling) it manually. aclocal throws a warning there: acinclude.m4:1089: warning: underquoted definition of PHP_CHECK_SIZEOF. Compile stops as with pecl command. uname -a : Linux serial-experiments.de 2.6.26-2-amd64 #1 SMP Thu Nov 25 04:30:55 UTC 2010 x86_64 GNU/Linux Any tips/solution would be great, ideas would be awesome too since im at the end of my brain :)
