Hi Paolo

In general the entire documentation for thie platform is here: 
http://www.hp.com/go/nonstop-docs, In this case you'd probably want to look at 
the (currently) latest version of the C/C++ Programmer's Guide 
 , Chapter 13 Compiler Pragmas.

Hmm, reading is of advantage sometime, I just see that instead of the pragma, I 
can use a compiler switch -Wcolumns=c, so I should be able to get around that 
issue without those 2 patches, by just tweaking my cc wrapper script slightly 
(i.e. adding a -Wcolumns=32767, the maximum, to the switches it uses to call 
the real c89/c99 C/C++ compiler).
Rats! It doesn't work! Seems the Compiler switch does not precedence over the 

Bye, Jojo

Ugh.  Do you have any pointer to "#pragma columns" documentation?  How 
far does its scope extend, i.e. why is it affecting gnulib's stdint.h?
