It is the latter.  However, the whole point of --with-gnu-as is to correct that
choice, isn't it?  It only blows up on the java, so I would guess it is only
the java that is wrong.  I now know how to work around this, by fiddling with
$PATH, but am I correct in thinking that I should not have to if the confiure
were working completely correctly?


While looking for evidence in the config files to support this
hypothesis (comparing gcc with java) I found this gem:

brains hgs 210 %> tail config.log
configure:7634: checking assembler dwarf2 debug_line support
configure:7690: checking assembler --gdwarf2 support
configure:7719: checking assembler --gstabs support
configure:7747: checking linker PT_GNU_EH_FRAME support
configure:7762: checking whether linker eh_frame optimizations work properly
  5 .eh_frame_hdr 00000024  000003b4  000003b4  000003b4  2**2
conftest.s: Assembler messages:

Please report this bug.
configure:7992: checking whether to enable maintainer-specific portions of Makefiles
brains hgs 211 %> pwd
/apps/hgs/gcc-build/gcc
brains hgs 212 %>

I get a different error on our Solaris2.7 box:


neelix hgs 87 %> tail config.log
configure:7537: checking for assembler offsetable %lo() support
configure:7634: checking assembler dwarf2 debug_line support
configure:7690: checking assembler --gdwarf2 support
configure:7719: checking assembler --gstabs support
configure:7747: checking linker PT_GNU_EH_FRAME support
configure:7762: checking whether linker eh_frame optimizations work properly
  5 .eh_frame_hdr 00000024  000003b4  000003b4  000003b4  2**2
conftest.s: Assembler messages:
conftest.s:54: Fatal error: conftest.s:31: bad return from bfd_install_relocation
configure:7992: checking whether to enable maintainer-specific portions of Makefiles

Both of these could be due to picking up the wrong as.

To save fiddling with $PATH (which may upset something else) does the
configuration procedure check for gas before checking for as -- i.e if I
symlink /usr/locla/bin/gas to /usr/local/bin/as will that fix things?

My path does have /usr/local/bin in it, but it is towards the back:
brains hgs 212 %> echo $PATH
/bin:/usr/bin:/progs/forte6/SUNWspro/bin:/apps/jdk1.2/bin:/usr/ucb:/usr/sbin:/usr/ccs/bin:/etc:/usr/local/bin:/usr/local/mysql/bin:/users/bin:  plus a bunch
of other stuff you're not interested in I expect!


        Thank you
