OK, I've figured it out.

The error was that gcc wasn't creating the identifiers L0000000000[5-8]\$pb in
the assembly file (though it was creating L0000000000[1-4]\$pb). Undoubtedly a
bug in gcc-4.2.1 (I tried building the one file with llvm-gcc and it worked.)

A bit of experimentation found that the bug is triggered by the combination of
-g and -O2. Turn off debugger output or change the optimization and it builds
fine. Since gtk-osx has its own debug flag setting, I just added
--disable-debug to the configure arguments (actually autogenargs for jhbuild)
and it's building OK.
