Since commit 1eb1dde049ccfffc42c80c2, Have make never delete
intermediate files automatically, I've frequently been getting errors
doing make -j2 after a maintainer-clean.
parser.c:25:21: fatal error: preproc.h: No such file or directory
compilation terminated.
make[4]: *** [parser.o] Error 1
make[4]: *** Waiting for unfinished jobs....
keywords.c:20:21: fatal error: preproc.h: No such file or directory
compilation terminated.
make[4]: *** [keywords.o] Error 1
make[3]: *** [all-preproc-recurse] Error 2
make[2]: *** [all-ecpg-recurse] Error 2
make[1]: *** [all-interfaces-recurse] Error 2
make: *** [all-src-recurse] Error 2
I don't see how the changes in that commit should cause this, but I
don't really understand make.
Cheers,
Jeff
