Thanks for the report.  This looks like a gnulib issue - the signbit[dl].o
files should have been included in lib/libm4.a (and not necessary in
M4_LIBOBJS in src/Makefile).  I'll let Bruno take a look at it, since he
manages the signbit module.

| Configure was called with: ./configure
| --prefix=/var/tmp/m4-root/opt/freeware
| The compile was done with gcc 4.2.3 on AIX 6.1 TL00 SP4
|
| This problem was not present in m4 1.4.10.
| In 1.4.10 the signbitd.o / signbitf.o / signbitl.o ware added
| automatically to the libm4.a.

And that should still happen with 1.4.11.

|
| Any ideas ?

Can you also post the config.log?
