Description
From keri@gentoo.org on mercury-users

===================

Hi folks.
                                                                                                                                                                                                                                                               
I've run into a hitch when bootstrapping mercury-10.04.1 on a linux-sparc box.
I'm attempting to bootstrap with mercury-10.04 where all C files need to be
rebuilt; I'm running a parallel compile with 32 submakes (it's a fast machine
:-)). It looks like building mercury_compile is failing due to race between
mmc generating .mih files and mgnuc compiling .c files that include the .mih
files.
                                                                                                                                                                                                                                                               
>From './configure':
                                                                                                                                                                                                                                                               
looking for an already installed Mercury compiler to bootstrap with...
checking for mmc... /usr/bin/mmc
checking whether the above mmc works and is sufficiently recent... yes
...
checking whether any C files need to be rebuilt...
there are no existing Mercury-generated C files

Without dialing things down to -j1, is there much I can do to workaround this
problem?
                                                                                                                                                                                                                                                               
                                                                                                                                                                                                                                                               
Thanks
