Hi Shane.
I came across this problem last week and only now checked in the appropriate changes which link in a new Mingwex library recently brought in by the Mingw32 team to cover some new C99 functions, one of which is the isnormal() function, which is in fact a macro in "math.h".
You need to get the latest Mingw runtime from
and install as usual. 
Do a CVS update to get the changes.
Then "make clean", configure etc and rebuild per the instructions in README.mingw.
Note that there is a new gcc v 3.1 compiler, which I haven't yet tried on GCL yet.
Mike Thomas.

  I just started trying GCL yesterday for the first time, and I tried compiling it on my Win98 box with the mingw compiler, following the instructions in readme.mingw.  It had problems compiling o/num_co.c, due to the recent changes in revision 1.3 of that file.
  In my compilation, the recent addition of two calls to isnormal() causes the linking step to fail, as isnormal() doesn't seem to be found anywhere.  Sorry, I don't know enough about isnormal() (or GCL) to provide a patch, but I was able to work around the problem by commenting out the isnormal() calls and the appropriate sections of the surrounding if statements.
