I built gcc-2.7.2 on my HP-UX 9.05 system (without gas) successfuly
but I need debugging information so I rebuilt it with gas but failed.
I did the following steps:

(1) built and installed GAS (from binutils-2.6) in /usr/local/bin/as
(2) build the target directory tree:
	$ make install-dir
(3) setup a symbolic link:
	$ ln -s /usr/local/bin/as
		/usr/local/lib/gcc-lib/hppa1.1-hp-hpux9.05/2.7.2/as
(4) run configure:
	$ ./configure --with-gnu-as
	This appears to be a hppa1.1-hp-hpux9.05 system.
	Using `./config/pa/pa.c' to output insns.
	Using `./config/pa/pa.md' as machine description file.
	Using `./config/pa/pa1-ghpux9.h' as target machine macro file.
	Using `./config/pa/xm-pahpux.h' as host machine macro file.
	Merged pa/x-pa-hpux.
	Merged pa/t-pa.
	Merged c++ fragment(s).
	Created `./Makefile'.
	Merged pa/x-pa-hpux.
	Merged pa/t-pa.
	Created `cp/Makefile'.
	Links are now set up to build a native compiler for
		hppa1.1-hp-hpux9.05.
(5) run make:
	$ make LANGUAGES=c
	<message deleted>
	mv tmplibgcc.a libgcc.a
	./xgcc -B./  -DIN_GCC   -g -I./include  enquire.o -o enquire
	collect2: ld returned 1 exit status
	/bin/ld: ./libgcc.a(
	__main.o): Not a valid object file (invalid system id)
	make: *** [enquire] Error 1

Can anyone built this before give me some pointers?  Thanks in
advance...
