   I understood that gcc as a cross for that group of targets only
worked with the configuration option --with-gnu-as ; if that is not
the case then what gcc configuration options should I be using?

   When I attempted to just configure gcc as

	./configure --target=hppa2.0-hp-hpux10.20

   as opposed to:

	./configure --target=hppa2.0-hp-hpux10.20 --with-gnu-as

then, when the xgcc is run to build libiberty it attempted to invoke a
non-existent assembler (e.g. the missing cross to HPPA gas) as shown
in the snippet below, specifically the cc1 phase warnings:

   What am I doing wrong? Any pointers would be greatly appreciated.
