www/firefox24 build failure with gcc 4.9.2 on Solaris 10 sparc

Hi,

I'm trying to build firefox24 with external gcc 4.9.2 on Solaris 10 sparc
and it's halting with the following error:

I have 'PKG_OPTIONS.firefox24+= -pulseaudio' in mk.conf for now.

All of the dependencies have built successfully to this point.

Anybody know why this is breaking even though there seems to be an
explicit patch for Poison.cpp on Solaris in the pkgsrc patches folder?

Thanks!
