Note: I was able to compile it in the same conditions with last Friday's (Feb 10 2012) git. With today's (Feb 13) I can't.

After ./bootstrap.sh and ./configure, the modules I enabled were:
xml_int/mod_xml_curl
endpoints/mod_rtmp
applications/mod_callcenter
applications/mod_curl
applications/mod_http_cache
applications/mod_voicemail_ivr

The craziest thing: when I go to /usr/src/cloudivr/freeswitch.test/src/mod/xml_int/mod_xml_rpc it seems that last gcc line ran OK! Re-running it confirms it. So, where does the error come from?
