You are right and what I wrote above is wrong. Gaby also has
pointed out that it is not currently realistic to depend on the
GCL binaries on Windows for Axiom development.

As far as I can tell no one has posted any binaries for GCL on
windows newer than

  gcl_2.6.6.mingw32_cltl1_japi_20050210.exe 22-Mar-2005



And gcl-2.6.8pre is still a "pre-release". I guess the gcl
project is also critally lacking in resources. If it would be
helpful I could certainly upload a windows binary of this
pre-release to the Axiom Wiki web site. But I am discouraged
also by Gaby's observation that there does not seem to be much
interest in development of the Windows versions of GCL or
Axiom. :-(

MinGW is required in order to compile Lisp to object code and
of course to compile the Lisp output of the SPAD compiler in
Axiom. Unlike Linux, it is not correct to assume that a C
compiler is available in the basic window installation. The
existing binary installer that I prepared for Axiom on Windows
includes the necessary parts of MinGW to permit GCL and Axiom
to compile object code. I think a similar binary installer
for GCL should include these same parts of MinGW so that the
GCL installation will be complete and fully functional.
