2.4.0-ac1 : 'make dep' drivers/acpi error

[Frank Davis]

Hello,
     I just downloaded 2.4.0-ac1 , and received the following error
during 'make dep':

make -C acpi fastdep
make[4]: Entering directory `/usr/src/linux/drivers/acpi'
/usr/src/linux/Rules.make:224: *** Recursive variable `CFLAGS' references
itself (eventually).  Stop.

I saw Keith's email about moving to make v3.77 or v3.79, if you are using
v3.78 . I confirmed that I am using make version v3.77 . So, it appears
that v3.77 doesn't work to compile drivers/acpi .
Should we look into patching Changes to make 3.79 the minimum version for
make, or 'fix' drivers/acpi (Makefile, Rules.make, etc.)? Has v3.79 been
confirmed to work? I understand v3.78 is confirmed broken.

Regards,
Frank
