[Ndiswrapper-general] [PATCH] strengthen kbuild dependencies on *_export.h

[Kel M. <ke...@ot...>]

Attemping to invoke the following build process fails:

~/tmp/ndiswrapper-1.53/driver$ make -C /lib/modules/$(uname -r)/build SUBDIRS=$(pwd) modules
make: Entering directory `/usr/src/linux-headers-2.6.25-10.slh.1-sidux-amd64'
  CC [M]  /home/kelmo/tmp/ndiswrapper-1.53/driver/crt.o
/home/kelmo/tmp/ndiswrapper-1.53/driver/crt.c:17:25: error: crt_exports.h: No such file or directory
make[1]: *** [/home/kelmo/tmp/ndiswrapper-1.53/driver/crt.o] Error 1
make: *** [_module_/home/kelmo/tmp/ndiswrapper-1.53/driver] Error 2
make: Leaving directory `/usr/src/linux-headers-2.6.25-10.slh.1-sidux-amd64'

The kbuild dependencies on *_exports.h are too lax. The following patch was
discussed here: https://bugs.launchpad.net/ndiswrapper/+bug/241547

Thanks, Kel.
