Hi all,

I have successfully build Ruby 1.5.3 under Tru64 with native compiler.

   > uname -a
   OSF1 slbhdg V4.0 1229 alpha  
   > cc -V
   Digital UNIX Compiler Driver 3.11
   DEC C V5.9-005 on Digital UNIX V4.0 (Rev. 1229)

But I have to change the line 

   CFLAGS = -g

to 

   CFLAGS = -oldc -std -g

After this, the interpreter could be build (issuing many many
warnings). The testsuit runs successful afterwards.

Could the flags be considered in future? 

I have to admit, that this is not Ruby's fault alone. It was resulting
from a combination of Ruby's old K&R-C coding style, the system header
files partially in ANSI-C and the native compiler which got confused
by all of these. :-)

Thanks,
\cle.
