2018-07-21 Paul Boddie file changeset files shortlog Invocations in parameter lists may require temporary storage for contexts and accessors, but the storage locations must be different. Otherwise, the code will generate a sequence-point warning. Here, distinct ranges for parameters in lists are introduced, and accessors are now also stored in arrays, permitting distinct storage.

Native library functions for character set conversion.

None of these are actually defined here. Instead, native implementations are
 
 paul@380      7 
substituted when each program is built. It is, however, important to declare
 
 paul@380      8 
non-core exceptions used by the native functions because they need to be
 
 paul@380      9 
identified as being needed by the program.
