RE: cross gcc - working gcc, but cannot compile C++

[Danny Backx <danny dot backx at scarlet dot be>]

Dave,

I'd used some search engines for the -Qy error but never really found
the solution. Your reply prompted me to do that yet again, and I found 

http://www.cygwin.com/ml/cygwin/1997-06/msg00457.html

which basically says

  configure creates a softlink in gcc object directory to the new
version of the cross assembler. Problem is that the native compiler
get confused and use the cross assembler instead of the native one.

So I looked inside the build/gcc/gcc directory and found a file
called "as" with the contents

#!/bin/sh
exec /usr/ppc/bin/arm-wince-pe-as "$@"

Renaming that file made the build progress beyond my initial problem.

I think this is a bug in gcc/g++. Right ?
