MODVERSIONS problem

[Timur Tabi <timur.tabi@xxxxxxxxxxx>]

I have a driver that is built outside of the kernel tree.  Our code 
handles different versions of the kernel (2.4 and 2.6), and recently we 
came across a kernel that needs to have MODVERSIONS enabled.  So, I 
added these lines to my makefile:

include ${LINUX}/.config
ifdef CONFIG_MODVERSIONS
CFLAGS += -DMODVERSIONS -include $(LINUX)/include/linux/modversions.h
endif

Although this fixes the problem with the new kernel, it breaks with the 
Red Hat 9.0 kernel.  I got hundreds of errors when I try to compile, 
like these:

In file included from devnet.c:11:
/usr/ammasso/src/rh90/2.4.20-6smp-32/include/asm/processor.h:82: invalid

`kernel_thread_R_ver_str' declared as function returning a function

When I look at my .config file, I see "CONFIG_MODVERSIONS=y".  Why is 
that my driver compiles when I don't include modversions.h?  Shouldn't 
it have been broken all along?
