Thanks!  I built gmake, and it made a big difference.

Now I am getting the following error:

-----------( start
make[1]: Entering directory `/data/home/cjh/lisp/build/gcl-2.6.1/o'

-----------( end

(The extra -I flags to gcc were put into makedefs by me in an effort to
resolve this.)

A Google search brought up this:
http://article.gmane.org/gmane.lisp.gcl.devel/2195

The patches seem to be there, since the h/gclincl.h has:

----------( start
#ifdef IN_NUM_CO
#ifdef HAVE_ISNORMAL
#define _GNU_SOURCE
#include <math.h>
#define ISNORMAL(a) isnormal(a)
#else
#ifdef HAVE_IEEEFP
#include <ieeefp.h>
#define ISNORMAL(a) (fpclass(a)>=FP_NZERO)
#else
#error "No isnormal found"
#endif
#endif
#endif
----------( end

The FreeBSD box I am using for this has multiple copies of math.h,
float.h and ieeefp.h, so I would guess that HAVE_ISNORMAL is undefined
for some reason.

----------( from config.log

/tmp/ccPOVE5t.o(.text+0x30): undefined reference to `isnormal'
----------( end config.log

Is there specific version of float.h that I need to use?

I've tried GCL 2.6.1-36 and 2.6.1-37 - same error.

Aloha,
