Well, the reason is "debug" ;-)

If I omit debug, then it works perfectly. But I'm trying to create a 
DEBUG build.

I've tried something similar already myself, but this change doesn't 
help. As you can see in the attachment, it only works for a plain make. 
With "make debug", it still fails. It must have something to do with the 
following definition in Makefile

	DEBUG_CFLAGS = -mtune=pentiumpro -O -Wall -D_REENTRANT 
-D_FILE_OFFSET_BITS=64 -DXINE_COMPILE -g -DDEBUG

but simply exchanging CFLAGS with DEBUG_CFLAGS in the above sed 
instruction didn't help.

That's why I cannot supply a fix for this issue and ask for help.

Bye.
