libmpc.a can be used on single-processor systems, and with single
process applications.  There is a *slight* performance penalty if your
application is a single process, because all stdio and memory
allocation routines are semaphored.  (It is very slight, because the
semaphore will never block if the application is a single process).

And of course, you're application will be larger, because libmpc is not
a shared library.
