I cannot recommend these patches for grx23. They make the library
compile but now you get a runtime error which I could 
track down to the inline asm lines in utils/shiftscl.c that were patched.
Meanwhile I got a precompiled version of the library (compiled with gcc 2.8.1)
which works correctly (well, at least here...).

The problem seems to be related to "cx" which is used as a dummy register there.
As I am no asm expert I can only make some guesses what's actually happening.

Is there some asm guru out there that can look into a 10-line inline asm
code that used to work with gcc 2.8.1 ?
