So far so good.

(1) depends on PATH setting obviously, which is ok from your PATH
listing (deleted). Are you using bash? If so, what does `type gcc'
produce? Can you run the following:
  
  $ gcc -v

and if yes, what does it say?

(2) is because of non-ANSI behaviour in lots of old code where instead
of include errno.h, the code declares an "extern int errno" which is
wrong.

Why can't you just look in the code to see what might be causing this?
Blindly running make and expecting everything to come out ok is probably
asking a bit too much.

I'm attaching my local changes to pbmplus ... comes w/out any warranty
whatsoever (TRANSLATION: free to take what you need, but please don't 
ask me questions about it).
