Trivial extern C linkage, but that still leaves the config/make issues. Let me 
remind you..

 * -funit-at-a-time - Not supported by some versions of gcc

 * --without-[rtai|rtlinux|rtlinuxpro] - Requires a valid path.

 * Running depend in the docs tree after --disable-build-documentation given

 * Running depend with a `make clean` target

 * Dumping logs to user's home directory - Inconsistent with LFSH

 * Hard coded kernel dependencies in runtime scripts/binaries

There is also a runtime problem on shutting down - The error:

Shutting down and cleaning up EMC2...
ERROR:  Can't remove RTAI modules, kill the following process(es) first

                     USER        PID ACCESS COMMAND
/dev/rtai_shm        paul      11284 ....m  hal_manualtoolc
Cleanup done


In it's self, not a major issue, but any further attempts to run emc fail. 
Manually removing any offending modules still loaded results in an unstable 
system that requires a cold reset - Probable cause - shared memory is not 
being released on exit by one or more processes.
