Probably make gets SIGBUS, which obviously won't be in the
for the sake of keeping information segregated in log files (and
balancing out test times)
I tried the following (from within a regression testing script):
'make -k check-gcc-c RUNTESTFLAGS=$runTEST >${STATE}/$svnRevision-
check-c-log.txt 2>&1' &
(sleep 2) 'make -k check-gcc-c++ RUNTESTFLAGS=

How? Last I tried, it didn't work, as mpc used the system gmp/mpfr,
not the just-built in-tree versions. Therefore, it's not really an
"in-tree" build, and you can't build on a system that doesn't already
have gmp
