Since bug 463385 modified extensions/Makefile.in to use PARALLEL_DIRS instead of DIRS for all extensions we have a race condition when doing parallel builds of schema-validation and xforms.
xforms (in http://hg.mozilla.org/xforms/file/3bd9353a5347/Makefile.in#l101) adds schema-validation to its DIRS, causing it to be built twice in parallel (once from extensions/Makefile and once from extensions/xforms/Makefile). This may work from time to time, but generally gives errors like this one:

Neil, since you made this change initially, do you have an idea how to solve this? Or could you CC someone else that might know how? ;)
ah wrong bug, I meant bug 462381 and that means Mitchell instead of Neil. The question above stays the same. Sorry for the confusion.
Ah, so xforms depends on schema-validation, and unconditionally builds it? Can you not remove schema-validation from your --enable-extensions list?
Thanks Neil, that seems to work indeed (simple and easy!) It only needs a small patch to the configure.in to remove the enforcement of that schema-validation dependency. I've attached a patch, but I'll do some more tests on different platforms before asking for review on this one.

Requesting approval2.0 because we need this for XForms to build reliably with Gecko 2.0.

[for checkin] configure.in changes
Philipp, did you start try server build? That's good guarantee the patch is safe to checkin?
yes, it builds on all platforms.
