Subject: Cross-compiling Linux kernel

 Hello!

 In order to cross-compile Linux kernel i have to patch host-side tools a
little bit. Current problems are:
 1. Cygwin misses linux/types.h
 2. Cygwin defines the following ELF macros according to host machine:
ELF_ST_BIND, ELF_ST_TYPE, ELF_R_SYM, ELF_R_TYPE

 What about improving Linux compatibility ? We could have own version of
linux/types.h (for __u8. __u16, etc), and omit ELF definitions. AFAIK they
are not used anywhere, they are just inherited from BSD.
 At the other hand, i believe the same problem will happen if i try to
cross-compile Linux kernel under BSD. And Cygwin is BSD-style system...

 Just decided to drop this in as one more "what if...".

Kind regards,
