problems compiling

[Rodrigo Moya]

Hi all!

I just updated my local copy of mtd from CVS (after a long time without
doing so), and now, I get the following errors when compiling:

make[5]: Circular /usr/src/linux-2.2.12/include/linux/compatmac.h <-

Looking at the sources, I've seen that the DECLARE_MUTEX is declared in the
sysdep-2.2.h file, but into a:

#if LINUX_VERSION_CODE < KERNEL_VERSION(2,2,0)
...
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,3,0)
...
#endif
#endif

I've been looking at the kernel sources to see which LINUX_VERSION_CODE was
defined, but haven't found nothing I could understand, so please help me.
It seems to me that an incorrect LINUX_VERSION_CODE is being defined, so
the compilation never reaches the line where the DECLARE_MUTEX is defined.

I'm using kernel 2.2.12 (the one shipped with RH 6.1)

Thanks
