I wanted to remerge mozilla-firefox 1.0-r3 today, and it failed. I did build it before, where it worked, though. Looking at the error messages, I thought it was some cairo (mozsvg) related problem, and was able to fix it. I got this error now and not before because the other time I had Cairo 0.2.0 on my system, 0.3.0 now. Adding an inclusion of "cairo-xlib.h" to one file and "stdlib.h" to another one fixed all issues. I cannot remember which files though, sorry. I did not try to "reproduce" this because building firefox is a terrible thing ;)
Beware mozilla folks, cairo-0.3.0 changed the header layout significantly to break out the various components.

Please see bug #80301 for a patch to the mozilla sources to work with cairo-0.3.0. @Mozilla herd: can we consolidate bugs #80301, #80637, and this bug, as they are all the same problem due to the new cairo version?
This one specifically has been resolved - looking at incorporating the same fix into mozilla itself.
