/* Gcd.c
compute GCD using Euclid Algorithm
eg, GCD 156562431911123 442677773754356 = 7
Source to GCD.BIN. Rebuild with Borland C++:
bcc -c -mt! gcd
tlink x02 gcd /t/x/c,gcd.bin,,fp ld
If you are using a coprocessor, you can also build with:
bcc -c -mt! gcd
tlink x01 gcd f87 /t/x/c,gcd.bin,,fp ld
With older versions of Borland C++ (Turbo C), compile with:
tcc -c -mt gcd
