[Bug ada/29157] New: gnattools fail on cross compilation - Makefile bug?

["belandor at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

I'm trying to build a cross-ada compiler (using different toolchains) with
gcc-4.1.1 or gcc-4.2.0-20060919.

In both cases, when building the last stage, the make process fails building
gnattools (i.e. gnattools-cross).

Error message:
make -C ../gcc/ada/tools -f ../Makefile \

So it seems, that the include directories for gnatmake are not properly passed
on (-I and several paths without -I). In addition, there should be a file name
at the end of the command line.

This happens reproducably with gcc-4.1.1 and the current gcc-SVN, using uClibc
and using a glibc C target, as well as rtems.

BTW: to get gcc-4.1.1 GNAT compiling, I exchanged s-wchcon.ad[bs] with the
current SVN versions.
