Version history
2.3
Make function declarations static in order to avoid conflicts with those from libc if the OS supplies them. This makes SHA-1 work on OpenBSD (thanks to Alan Post and Christian Kellermann)
2.2.2
Change deprecated pointer foreign type specifier to scheme-pointer to make it work under chickens newer than 4.6.0.
2.2.1
Fix for test, wrong context allocation size. Kon Lovett
2.2
a message-digest-primitive has no "state". Kon Lovett
2.1
Replaced GPL code with common public domain code.
2.0.0
Initial Chicken 4 release Kon Lovett
