scala use of GMPUtil for pidigits

Rex Kerr has posted info about using GMP with scala, in particular to run the pidigits program. libjpargmp.so is generated using G开发者_运维百科mpUtil.c

My question is: where do I find GMPUtil.c? My google searches haven't turned up anything.

Regards, Doug

Posting on the Alioth computer languages benchmark game forum would more likely yield an answer than posting here. However, in this case you've gotten lucky (though I don't know if this is exactly an appropriate use of StackOverflow).
