I hadn't heard of the Collatz sequence before, and read up a little on
it today. Also saw some of your correspondence on sci.math.

About the linker problem with g++ on Cygwin, I have run into it several
times, and have discovered that re-ordering your libraries works
sometimes. For example, on my system,

g++ -lgmp -lgmpxx pi.cpp
generates large numbers of "undefined reference" errors, but the
following works just fine:

g++ pi.cpp -lgmp -lgmpxx

(i.e., put the source file name before the libraries). No idea why it
works, though.
