Strings in GPC (was: GPC question)

According to Jesper Lund:

The GNU Texinfo online documentation of recent beta versions of GPC
contains a complete list of all built-in identifiers - most of them
without explanation, sorry, but it's a start.

Correct.  If you say "Function Foo: String", GPC accepts it as a string of
length 255 but warns about it (unless you are in `--borland-pascal' mode).

According to Extended Pascal, strings are written with parentheses
("Str255 = String ( 255 )"), but GPC also accepts UCSD/Borland syntax
("Str255 = String [ 255 ]").  In the future we *might* change this such
that GPC produces an Extended Pascal string (unlimited length, 8 bytes
overhead) with "(...)" but a Borland Pascal string (limited to 255 chars,
1 byte overhead) with "[...]".
