Bootstrapping pkgsrc on SCO OpenServer 5 (GCC 4.2.4) and SCO OpenServer 6 (GCC 7.3.0)

[Lance Payne <lance.payne%poorfellow.org@localhost>]

Hello,

Has anyone had any luck bootstrapping pkgsrc on OSR5/6 Definitive with the full 
native and GNU compilers?

The errors vary on each platform, normally with awk (6) and sed (5).  Here is 
the latest aborted bootstrap from 5:

process.o -lnbcompat

I appreciate any assistance.
