According to Tom Dye:

[...] This code, which compiled previously, fails now with a message that there is an undeclared identifier `Ch' in function Isalphanum on line 17.

***-------------------------------------*** module charbug interface; [...] function IsAlphaNum (ch : char) : boolean;

module charbug implementation; [...] function IsAlphaNum;

You have detected a bug in gpc-971001 which fails to attach the correct header "(ch : char) : boolean" from the interface declaration to the header in the implementation module.

To work around, repeat

function IsAlphaNum (ch : char) : boolean;

in the implementation module; the bug will be fixed as soon as possible.

Hope this helps,

Peter
