missing/vsnprintf.c defines some macros like clearerr and ferror,
which are already declared as functions in stdio.h. Although
vsnprintf.c is not including stdio.h, it seems like cpp includes it
after preprocessing vsnprintf.c and then I get those errors
("Redefinition of macro clearerr" because stdio.h is declaring it as a
function, after being defined as a macro in vsnprintf.c, etc)

I'm new at HP-UX, I'm missing something important for sure. Changing
the flag -Ae for -Aa "solves" the problem for vsnprintf.c. But then I
get other errors when running miniruby.

I'll try with 1.8.4-preview1 and see

Yes, it is missing.

HP-UX 11 already has vsnprintf AFAIK.

I have just found this:

http://www.ruby-lang.org/ja/install.cgi?cmd=view;name=HP-UX

It explains how to solve some problems I ran into. It says something
about vsnprintf and a patch for HP-UX, but I can't read Japanese :( 
Does any caritative soul want to help me? (from the line starting with
"missing/vsnprintf.c", almost at the end of the file)

Thanks in advance
