Nico,

 

thanks for warning.-) So far I’ve been using the GMP on Win32 to my (almost 
fullest :-)) satisfaction.

Please be aware that the GMP library is a GNU library and hence not
every productive Unix system in the world will have it installed.
You have to decide whether to go with:
- an approach that not only requires additional libraries
on your clients' machines (GMP) but also refers to
another runtime system (GNU runtime);
- your own code which will be portable across all supported
platforms but which you will have to maintain yourself;
- a "standard" library which is not available under Windows
(namely "mp", the Multiple Precision library under Unix).

Should you consider the latest one (using mp), be warned that not only
Windows does not have a MP library but also it's completely different
in handling than the GMP library.

[Sigh. This is one of the areas where I love the standards set by Sun
for Java; one code to run everywhere; as long as you don't stumble
across errors in particular implementations...]

Regards,
Nico
