Hello.
I updated the Debian package for m4 and now it does not build ok in
alpha and hppa (Linux in both cases).
This is what happens in alpha:
-------------------------------------------------------------------------
gcc -DEXEEXT=\"\" -DEXEEXT=\"\" -I. -I../lib -DIN_M4_GNULIB_TESTS=1 -I. -I.
-I.. -I./.. -I../lib -I./../lib -Wdate-time -D_FORTIFY_SOURCE=2 -mieee

test-sys_stat-h.c

-------------------------------------------------------------------------
and this is what happens in hppa:
-------------------------------------------------------------------------
Checking ./stackovf.test
Stack soft limit set to 8192K
Failure - m4 aborted unexpectedly
Output from m4:
m4: internal error detected; please report this bug to <bug-m4@gnu.org>:
Segmentation fault
Skipped checks were:
./127.changeword ./128.changeword ./129.changeword ./130.changeword
./131.changeword ./132.changeword ./133.changeword
Failed checks were:
./stackovf.test
make[4]: *** [Makefile:2574: check-local] Error 1
-------------------------------------------------------------------------
It might be worth to mention that this used to work five months ago
with 1.4.19, so this is a regression.

Thanks.
