Error building H8/300 cross compiler

[Manfred Metzger <ManfredMetzger at swol dot de>]

Iīm trying to build a crosscompiler for H8/300 on Linux with:

../configure --prefix=/usr --target=h8300-hms
--with-newlib                                                                   
make cross

It always fails configuring libf2c with the following output:

This happens at least with egcs-980302 and egcs-980308. It worked with
an older
snapshot (I canīt remember which one).

Another question: Is it possible to compile the crosscompiler with
specific 
optimization flags? make BOOT_CFLAGS=... does not work.

Thanks
