building GCC 4.0 for arm-elf target on mingw host

[Dave Murphy <wintermute2k at ntlworld dot com>]

Hi,

I've been attempting to build the gcc-4.0 20050319 snapshot under 
mingw/msys for arm-elf target with a few problems.

the mingw32 gcc is 3.4.2

Configuring seems to work fine.

../../$GCC_SRCDIR/configure \
   --enable-languages=c,c++ \
   --enable-interwork --enable-multilib\
   --with-gcc --with-gnu-ld --with-gnu-as --with-stabs \
   --disable-shared --disable-threads --disable-win32-registry 
--disable-nls\
   --target=arm-elf \
   --with-newlib \
   --prefix=c:/devkitARM_r12


proceeding with make all-gcc results in a number of weird errors 
configuring in subdirectories

Configuring in intl
make[1]: Entering directory 
`/c/projects/devkitPro/sources/arm-elf/gcc/intl'
make[1]: *** No rule to make target `all'.  Stop.
make[1]: Leaving directory `/c/projects/devkitPro/sources/arm-elf/gcc/intl'
make: *** [all-intl] Error 2

The build process doesn't stop but carries on with configuring (in some 
cases displaying the command prompt as if the build had stopped). 
Removing the files from the subdirectory in the build directory & 
restarting make all-gcc allows me to continue but results in the same 
error in a number of subdirectories.

After 3 or 4 restarts it finally appears to proceed normally until 
building libgcc

copying the compile line and removing the spurious -I and the 
-I../../../gcc-4.0-20050319-new/gcc/ results in no errors.

I'm having a little trouble finding where this line is built up in the 
makefiles, can anyone point me in the right direction to solve this problem?
