on AIX 6.1 two objects are missing from the libm4.a.

Making all in src
gmake[2]: Entering directory `/opt/freeware/src/packages/BUILD/m4-1.4.11/src' gcc -std=gnu99 -g -O2 -o m4 m4.o builtin.o debug.o eval.o format.o freeze.o input.o macro.o output.o path.o symtab.o stackovf.o ../lib/libm4.a -lm

gmake: *** [all] Error 2

If I add signbitd.o and signbitl.o to M4_LIBOBJS (in src/Makefile) then the link is successful.
With this "fix" all tests from make check are successful.

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.

Any ideas ?
