It doesn't compile on my machine (Mac OS X 10.6):

gcc -c  -Demacs -DHAVE_CONFIG_H  -I. -I/Users/dr/em23/src -Dtemacs     -g -O2 -Wdeclaration-after-statement -Wno-pointer-sign   -MMD -MF deps/dispnew.d dispnew.c
In file included from lisp.h:3690,
                 from dispnew.c:31:
thread.h:128: error: thread-local storage not supported for this target
thread.h:142: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'global_lock'
make[1]: *** [dispnew.o] Error 1
make: *** [src] Error 2

That link suggests that the feature you're using is related to ELF and thus not portable.

Thanks for your work on this - looking forward to seeing the results!
