But you might have /more/ GNU stuff installed in default locations than I have.
For example, in the configuration I'll show shortly, it barfs on unsatisfied
symbol '__umoddi3', which can be found in libgcc.a, which I do not have
installed in a default location, and since I'm building with HPc, it won't
find it without hints. Now if I set LDFLAGS="-L/usr/local/pa20_64/lib -lgcc"
where libgcc can be found in my situation, it is put *before* the libs, making
the needed symbols unfindable, so I commented out LDFLAGS and put in
LIBS=/usr/local/pa20_64/lib/libgcc.a

FYI when reading on, /usr/local/pa20_64 is a symlink to /wrk/pa20_64 because
    that LV has more space to play with.

I used
