Both static and dynamic linking work on Windows if the right headers are
installed to declare functions properly. The fact that the GMP project
cannot organise its public headers properly is an irritation.

Performance may be faster on any platform using static linking
(depending on the details of the ABI and runtime linker).

GCC links GMP statically. Platform package manager updates to shared
libraries are more likely to cause breakage than static linking.
