The Algol68 compiler has been extended to support decimal radix (base 10) in bit denotations, implementing a GNU extension. This change is particularly useful for transput operations and Foreign Function Interface (FFI) calls where precise bit counts represented in decimal are needed. A compile-time diagnostic is also added to catch invalid radices.
