Error compiling bootstrap-gcc: canīt find signal.h

[Usabiaga Gorka <GUsabiaga at ikerlan dot es>]

Hi all,

	Iīm trying to build a cross compilar hosted on a cygwin-Win2k PC for
a linux based Geode GX (x86) embedded system. Iīm following
http://www.billgatliff.com īs CrossGCC FAQ and it fails building the
bootstrap-gcc compiler.

	The log file recorded from the building process goes as attachment.

	I'm trying with the following software:

	- Cygwin 1.3.2 (0.39/3/2)
	- Binutils 2.11.2
	- GCC 3.0.1
	- Newlib 1.9.0
	- GDB 5.0

	Have no problems building and installing the binutils package but
Iīm taking the next one on the bootstrap-gcc building process:

	I've configure the gcc package with 

	../gcc-3.0.1/configure --host=i686-pc-cygwin
--target=i586-elf-linux-gnu --enable-language=c --with-newlib 2>&1 |tee
configure_gcc.log

	and take no problems. Then I use this command to build it:

	make all-gcc install-gcc 2>&1 |tee make_gcc.log

	and take the error.

	I've omitted the --without-headers flag following the suggestions
from M.R. Brown's mail but this can't solve the error.

	Any new suggestions?

	Thanks to all in advance.
