Problem with German Umlaute

[Bernd Klein]

Hi,
since I've upgraded to SuSE 10.0 I have a problem with gcc (Version: gcc 
version 4.0.2 20050901), while SuSE 9.3 used
gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)

I can't read and write anymore any files which contain German Umlaute.
I am using the compiler option:

COMPILER= g++ -encoding=utf-8 -fPIC -Wall -Woverloaded-virtual -Wreturn-type 
-ansi -pg -Wno-deprecated

I googled around a lot but couldn't find anything which worked.

I hope that somebody knows a solution for me!

Best wishes,

Bernd
