Hi!
I just tried the self tests of m4-1.4.10 on NetBSD-4.99.23/amd64.
Two failed:
test-frexpl.c:167: assertion failed
[1] Abort trap (core dumped) EXEEXT="" EXEEXT...
FAIL: test-frexpl
...
test-printf-frexpl.c:103: assertion failed
[1] Abort trap (core dumped) EXEEXT="" EXEEXT...
FAIL: test-printf-frexpl
Debugging test-printf-frexpl.c gives:
(gdb) bt

Start it from the beginning? (y or n) y

I'm confused. Can someone else make heads or tails of it?
