I am very far away from home, sorry about the delay in replying.
The GCC 4.0 problem is already fixed in my development version.
The following is ONLY for Mac OS X 10.4, using compiler 4.0 or higher.
The problem is the compiler switches set by the configuration
script. For a temporary fix, run ./configure, then edit
the file "makefile" so that two lines near the top look like:
For G4 processors:
CFLAGS= -O4 -mcpu=7450 -mtune=7450 -fast
SAFECFLAGS= -O4 -mcpu=7450 -mtune=7450
For G5 processors:
CFLAGS= -O4 -mcpu=g5 -mtune=g5 -fast
SAFECFLAGS= -O4 -mcpu=g5 -mtune=g5
For G3 or lower processor, or for any compiler version before 4.0.0,
don't use the "-fast" switch. Probably this works:
CFLAGS= -O4 -mpowerpc
SAFECFLAGS= -O4 -mpowerpc
You could also try -mcpu=7400 -mtune=7400 but don't use -fast.
After editing "makefile", do "make clean", then "make".
If you run "configure", the file "makefile" is overwritten, so be
careful not to undo these changes.
Hope that helps. Brendan.
