It is working now. I'm not sure what the difference between my build
environment at work and at home is, but I have it working at home
(Ubuntu 7.04/i386) now. I should be able to get it to work at work
(RHEL 4/i386) too.

Here is what I did at home:

Download fpu_19.zip, uncompress (I used file-roller)
Install build-essential package (I was surprised Ubuntu can't compile
a C program be default)
Modify path so that current directory is included (in bash: PATH=.:$PATH)
cd to fpu_v19/test_bench/SoftFloat/softfloat/bits32/
cp -r 386-Win32-GCC 386-Linux-GCC
cd 386-Linux-GCC
gedit Makefile
remove the .exe after EXE =
back to shell
make

I do get warnings from make which I ignore

cp timesoftfloat ../../../..
cd ../../../..
chmod +x maketest.bat
vi maketest.bat
eliminate ^M at the end of every line (I hate Windows)

maketest.bat
vi testcases.txt (a very big file - which I don't know is correct yet,
but it looks reasonable)

PS: if you try to use the existing executable which presumably runs
under Windows, you get:
run-detectors: unable to find an interpreter for ./timesoftfloat
