You're an absolute star :)

Thanks for posting the patch. I got inspired to have another go at 
building an arm-elf Insight under mingw/msys. I've now managed to build 
Inisght 6.1 with gdb 6.3 up to a point. I have a functioning gdb but I'm 
having problems with some deprecated functions in gdbtk-cmds.c and 
gdb-register.c. Do you know what I need to use instead of these functions?

bfd_get_section_size_before_reloc'
DEPRECATED_REGISTER_CONVERTIBLE'
DEPRECATED_REGISTER_CONVERT_TO_VIRTUAL
DEPRECATED_REGISTER_VIRTUAL_SIZE

cross posted to gdb list in case anyone there can point me in the right 
direction.
