problem compiling crosschain

[Robert Schwebel <robert at schwebel dot de>]

Hi, 

I have problems compiling a crosschain for ARM. My gcc stage 2
compiler's cpp0 seems to have the wrong include paths compiled in.

The symptom is that when I try to compile a program which uses
sys/param.h the compiler doesn't find it. 

----------8<----------
# cpp0 -v
GNU CPP version 2.95.3 20010315 (release) (ARM GNU/Linux with ELF)
#include "..." search starts here:
#include <...> search starts here:
 /home/robert/embedded/ptxdist-0.3.3/arm-linux/lib/gcc-lib/arm-linux/2.95.3/include
 /home/robert/embedded/ptxdist-0.3.3/arm-linux/lib/gcc-lib/arm-linux/2.95.3/../../../../arm-linux/sys-include
 /home/robert/embedded/ptxdist-0.3.3/arm-linux/lib/gcc-lib/arm-linux/2.95.3/../../../../arm-linux/include
End of search list.
The following default directories have been omitted from the search path:
 /home/robert/embedded/ptxdist-0.3.3/arm-linux/lib/gcc-lib/arm-linux/2.95.3/../../../../include/g++-3
End of omitted list.
----------8<----------

I would think that the paths should be something like 

  /home/robert/embedded/ptxdist-0.3.3/arm-linux/lib/gcc-lib/arm-linux/2.95.3/include
  /home/robert/embedded/ptxdist-0.3.3/arm-linux/include

The compiler was configured with 

----------8<----------
PATH=$PATH:"/home/robert/embedded/ptxdist-0.3.3/arm-linux"/bin \
AR=arm-linux-ar \
RANLIB=arm-linux-ranlib \
CC=gcc \
/home/robert/embedded/ptxdist-0.3.3/build/gcc-2.95.3/configure \
	--target=arm-linux \
	--prefix="/home/robert/embedded/ptxdist-0.3.3/arm-linux" \
	--enable-target-optspace \
	--disable-nls \
	--with-gnu-ld \
	--disable-shared \
	--enable-languages="c" \
	--with-headers=/home/robert/embedded/ptxdist-0.3.3/build/linux-2.4.18/include \
	--with-headers="/home/robert/embedded/ptxdist-0.3.3/arm-linux"/include \
	--with-libs="/home/robert/embedded/ptxdist-0.3.3/arm-linux"/lib
----------8<----------

I suppose there should be less "--with-headers=" lines, but that was the
only way I could make it actually compile...
