Making use of Panda dist TOPS20

I'm trying to wrap my head around getting Mark Crispin's Panda Distribution of TOPS20 set up such that I can actually make use of a TOPS20 environment. I keep finding lots of manuals through Google searches, but I'm missing a few critical things. Things that are evading me are as follows:

KCC and parenthesis in preprocessor lines

I'm having some trouble getting Frotz 2.50 ported to TOPS20. Version 2.32 with dumb interface compiles fine under KCC. With 2.50, there are several preprocessor lines that include parentheses. For instance: #if UINT_MAX == (1UL<<32)-1UL typedef unsigned int uint32; #else typedef

Converting C for KCC on TOPS20

I'm trying to convert some C code[1] so it'll compile on TOPS20 with KCC. KCC is mostly ANSI compliant, but it needs to use the TOPS20 linker, which has a limit of six case-insentive characters. Adam Thornton wrote a Perl script[2] that successfully does this for Frotz 2.32. The Frotz
