OK, the first part was easy! I've built it and using a custom config
copying some defines from the TPF config to enable code page
conversions. I'm having problems with the build. The z/OS linker is
different in that it uses different options. Libtool is killing me here
as it's obscuring things. I would rather see the full verbose commands
instead of CCLD curl. Is there anyway that I can disable libtool or get
it to print what I need? I noticed that the TPF port uses it's own
Makefiles. I don't really want to do that but maybe that's the best option.
