Looks like gnumach-1.3.99.dfsg.git20110305 does not build from source
any longer:
make[3]: Entering directory
`/home/srs/DEBs/gnumach/gnumach-1.3.99.dfsg.git20110305/build'
if test -s gnumach-undef-bad; \
        then cat gnumach-undef-bad; exit 2; else true; fi
.L430
make[3]: *** [clib-routines.o] Error 2
make[3]: Leaving directory
`/home/srs/DEBs/gnumach/gnumach-1.3.99.dfsg.git20110305/build'

At least with gcc-4.6 and mach_port_deallocate_debug=1!
