egcs-2.91.60 on powerpc-ibm-aix4.3.2.0: internal errors with DDD 3.1.3

[Lassi A. Tuura]

Hi,

While compiling DDD 3.1.3 (the data display debugger) on
powerpc-ibm-aix4.3.2.0 I get the following errors (first the commands
and errors, then an elaborated version for one of the files):

If you need more information, let me know.  To repeat the bug, just
download the DDD 3.1.3 from http://www.cs.tu-bs.de/softech/ddd/ ,
configure and build (I've added option -Wno-return-type -Wno-trigraphs
to avoid gobs of warnings from X11 and other system headers).  I know
little about the internals of DDD myself, but am happy to help if
instructed what to do.  If you think you want preprocessed output, let
me know.

Cheers,

With sufficient thrust, pigs fly just fine.  However, this is not
necessarily a good idea.  It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead.  --RFC1925, "The Twelve Networking Truths"
