[PATCH] Don't install Cygwin specific files elsewhere

[Christian Franke <Christian.Franke@t-online.de>]

[-- Attachment #1: Type: text/plain, Size: 553 bytes --]

This patch prevents the install of grub.d/10_windows on other OS.

grub-pe2elf is only installed if requested by --enable-grub-pe2elf. Even 
on Cygwin, grub-pe2elf is only required during build.

2008-08-08  Christian Franke  <franke@computer.org>

	* Makefile.in: Add `target_os' and `enable_grub_pe2elf'.
	* conf/common.rmk: Install `grub-pe2elf' only if requested.
	Install `grub.d/10_windows' only on Cygwin.
	* configure.ac: Add subst of `target_os'.
	Check `target_os' also before setting TARGET_OBJ2ELF.
	Add `--enable-grub-pe2elf'.
