| Hi!

| m4-1.4.11 fails two selftests on NetBSD-4.99.48/amd64.

Hi Thomas, and thanks for the report.

Both of these failures are in the gnulib tests, hence I'm adding
bug-gnulib.  Could you please also run 'make -k check' to see if the
M4-specific tests pass?

| The first one is in test-frexpl:
|
| # gdb test-frexpl test-frexpl.core
| GNU gdb 6.5
| Copyright (C) 2006 Free Software Foundation, Inc.
...
| Core was generated by `test-frexpl'.
| Program terminated with signal 6, Aborted.

| 166           ASSERT (mantissa == 0.505L);
| (gdb) p mantissa
| $1 = 0.505
|
| The second one is in test-printf-frexpl:
|
| GNU gdb 6.5
| (gdb) fr 2
| #2  0x0000000000400db2 in main () at test-printf-frexpl.c:102
| 102           ASSERT (mantissa == 1.01L);
| (gdb) p mantissa
| $1 = 1.01
| (gdb)
|

These tests are from Bruno, so perhaps he has more ideas of what you
should probe for in gdb, such as examining the memory for the actual bit
patterns at work here.
