Greetings!  Yes, another user has posted about the needed upgrade

While bfd support has extended GCL's native code relocation ability to
arm, m68k, powerpc, s390, and amd64, fully justifying IMHO its use to
'offload' this functionality, its API is explicitly stated by its
developers to be subject to change like this without notice.  The
soname version of the library changes with each point release, making
the conventional means of tracking external backward-incompatible api
changes via shared library versioning extremely impracticable, as any
minor bfd shared lib change at all would force a gcl, maxima, acl2,
and axiom recompile.  Linking in libbfd.a statically extends the
binary life a bit, but can silently lead to problems, such as when
Debian's gcl was built against bfd 2.14, and then later used to build
axiom et.al. when bfd was upgraded to 2.15, leading to silent breakage
whenever intermediary build images are generated via

I'm coming to the reluctant conclusion that the best course for GCL is
to 1) effectively fork bfd and build from a local snapshot in the gcl
sources (--disable-statsysbfd --enable-locbfd to configure), or 2)
extend the older i386 and sparc only elf relocation code to the other
platforms.  2) means lots of work for sure, so 1) is best for now.

We can put in some configure magic to detect the external bfd version
and toggle the rawsize form accordingly, but this is too ad hoc for
words. :-)

Take care,
