It is not clear to me where the problem comes from. Could you please provide
a few more bits of info, to track this down?
1) Does the problem also occur if you build m4-1.4.11 after freshly unpacking
the tarball in an otherwise empty directory? ('cause the report could be
related to a mix of builds done on different systems.)
2) What is the output of
grep REPLACE_SIGNBIT config.status
and of
grep RANLIB config.status
3) Can you show the lines 401..453 of the generated lib/math.h?
4) What is the output of
nm lib/libm4.a | grep -i signbit
5) Does the link error go away if you change the src/Makefile line
m4_LDADD = ../lib/libm4.a $(LIBM4_LIBDEPS) $(POW_LIB)
to
m4_LDADD = ../lib/libm4.a ../lib/libm4.a $(LIBM4_LIBDEPS) $(POW_LIB)
?
