parallel bigloo builds fail

[NHOrus]

Successfully simulated failing builds with, say, MAKEOPTS="-j1 --shuffle=1852839864"

clang -I -I. -I/var/tmp/portage/dev-scheme/bigloo-4.5b/work/bigloo-4.5b/lib/bigloo/4.5b -fPIC -I/usr/include/gc -fPIC -I. -I /var/tmp/portage/dev-scheme/bigloo-4.5b/work/bigloo-4.5b/lib/bigloo/4.5b table.c -o objs/table.o -c
error: unable to open output file 'objs/table.o': 'No such file or directory'

Will provide patch when I'm sure I squished most of them.

Hi,

Thank you for the report (and thank you for mentioning Make's --shuffle option that I did not know). I don't fully understand your fix but I see that bdb's Makefile is wrong. I'm working on it.

Thanks again,

Basically, I throw explicit dependencies until it stops trying to compile in wrong order. And I also removing cd dir; make antipattern - there's make -C for that. Only thing worse is for list of dirs; cd dir; make - it can swallow errors silently and continue to compile. Instead of stopping nicely and early.

Ah sure. You are absolutely right. Thanks for your help and your contribution. I will upload a new version soon.
