Might be one of the "fragile" substitutions:
 ${action#-}
 ${action#?}
 address@hidden
introduced recentlish in the msvc branch.

Running the ar-lib script with traces might be enough to pinpoint
the bug.

Seems like a limitation (bug) of the find utility; what I'd do is
replacing the above find command simply with:
  find ../foo-1.0
WDYT?

Might be one of the "fragile" substitutions:
 ${1#-I}
 ${1#-l}
 ${1#-L}
 ${1#-Wl,}
introduced recentlish in the msvc branch.

Running the compile script with traces might be enough to pinpoint
the bug.

Re-running the tests with `/bin/ksh -x' might really help here.  No idea
what might have ben gone wrong otherwise.  And yes, this is clearly a bug
introduced by my recent "instspc.test refactoring" patch.

This failure seems unrelated with the latest testsuite work.  The only
recentish change affecting this file is:
  v1.11-62-g0344911 "Avoid generation of `tests/defs-p' file"
but I doubt it could be the cause of the failure.

This might be a real automake bug (unportable rules in lib/am/check.am,
maybe?).  Just wild guessing, though.

The only other remotely possibly relevant change I might think of is:
  v1.11-159-ge7aa360 "Work around a nasty bug (segfault) of Solaris make."
modifying the `recheck' rules in `lib/am/check.am'.  But a quick glance
to the diffs shows that this change should be harmless w.r.t. this
testsuite failure.

... but the C compiler is clearly not gcc-compatible in this respect.

My bad I guess.  The solution might be splitting silentlex.test in two
sister tests:
 - silentlex-generic.test, trying only default depmode and disabled
   depmode; and
 - silentlex-gcc.test, trying trying gcc depmode and having `gcc' in
   $required.

And maybe something similar should be done for silentyacc.test too.

Opinions?

 commit f19b07647af068030866b7bc94710e930a6fccb9
 Author: Ralf Wildenhues <address@hidden>
 Date:   Sat Oct 2 20:26:47 2010 +0200

    Coverage and minor fixes for variable typo detection.
    
    * automake.in (check_typos): Remove `EXTRA_' prefix when
    computing canonical name.
    * tests/vartypo2.test, tests/vartypos.test: New tests.
    * tests/Makefile.am (TESTS): Update.
    
    Signed-off-by: Ralf Wildenhues <address@hidden>

I guess Ralf will take care of those ;-)
