           Summary: cairo-1.10.0 fails to build on darwin due to pthreads
                    issue
           Product: cairo
           Version: 1.10.1
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: general
        AssignedTo: cworth at cworth.org
        ReportedBy: jeremyhu at freedesktop.org

cairo assumes that pthreads are not available, then it fails to build:


./configure  --prefix=/opt/X11 --disable-static --disable-dependency-tracking
--disable-nls --cache-file=/tmp/X11libs.roots/X11libs~obj/configure.cache
--x-include=$X11_PREFIX/include --x-lib=$X11_PREFIX/lib --disable-quartz
--enable-xlib --enable-xlib-xrender --enable-xcb --disable-specs
--disable-devel-docs 
...

config.log shows that the conftest.c tests succeeded, but you still chose to
