I assume it fails on some of the larger files which, in typical
Fortran style, are just one huge function. Is it possible to compile
just that one file, without loading all the rest? And then load up
all of maxima later, as if you had used full Allegro to compile the
files?
Just a thought. I'm not actually suggesting this be done, except for
those who really must want to compile and use maxima using Allegro
Express.
BTW, LAPACK dgesvd is about 3500 lines of Fortran code all in one
function. This is translated to 6000+ lines of Lisp, and takes
several minutes to compile in CMUCL.
