Missing C Standard files from kernel source and module headers

[rcbpage]

Trying to compile modules for LIRC, Parallels VM and VirtualBox VM.
Seems there are critical files missing from the Linux source and consequently from the resulting header packages.
Missing Include files: float.h, stdarg.h, possibly more?

Any Help with this would be appreciated.

After some hunting around I found the following allowed me to compile kernel module under Natty.

$ cd /lib/modules/$(uname -r)/build/include
$ sudo ln -s $(gcc -print-file-name=include)/stdarg.h

This links stdarg.h to where the kernel makefiles will find it when it’s #included from the various kernel header files in Natty.
