Re: FYI: test case for rebuild rules and make -j

[Akim Demaille]

| I'm installing this on HEAD.  This tests `make -j' with rebuild rules.
| Although this requires CVS Autoconf I've not added an AC_PREREQ
| to the test case.  This is because Automake 1.8 will require
| Autoconf 2.58.  (autoreconf's support for the new aclocal is the
| main reason.)
| 
| I've found two bugs while working on this patch
|   1. the rebuild rules for Makefile failed to propagate automake's
|      exit status.  This is fixed in this patch.

Good catch!  This is a major cause of failures in EPITA Tiger
Projects (I was just tracking it down...)

|   2. the locking code of autom4te failed to obtain an exclusive
|      lock.  There is a pending patch for this in address@hidden

I'll go and read it now :)  Thanks in advance!
