If I understand correctly the issue at hand is multiple concurrent
rebuild rules, from a single parallel make implementation, are each
invoking autom4te concurrently and since file locking didn't work,
they clobber each other and things go wrong.
That is what would happen, but what currently happens is if the file
locking does not work and a parallel build is used, then Autotools
reports a hard error:
CDPATH="${ZSH_VERSION+.}:" && cd /home/bfriesen/src/graphics/GM &&
/bin/sh '/home/bfriesen/src/graphics/GM/config/missing' aclocal-1.16
-I m4
autom4te: cannot lock autom4te.cache/requests with mode 2: Invalid
argument
autom4te: forgo "make -j" or use a file system that supports locks
aclocal-1.16: error: autom4te failed with exit status: 1
gmake: *** [Makefile:4908: /home/bfriesen/src/graphics/GM/aclocal.m4]
Error 1
In my case there is only one active developer so there would not be
actual corruption.
