 Hello,
 
 would it be possible for the submitter to check and see whether this  
 problem still occurs on gcc 3.3? Thanks,

>Environment:
building an sh4 xcompiler on a mandrake linux intel system
>Description:
The file gcc/configure does not set inhibit_libc if --without-headers is set, as this translates to --with-headers=no. So the bootstrap fails in compilation.
 This is my own personal patch, which I urge you to study closely.
>How-To-Repeat:

host=i686-pc-linux-gnu
build=$host
target=sh-linux-gnu

	../../gcc/configure \
		--target=$target \
		--prefix=$prefix \
		--host=$host \
		--build=$build \
		-v \
		--without-headers \
		--enable-languages=c \
		--with-cpu=sh4 \
		--disable-threads
	make all install
