Eric,

can you take a look at Paul's documentation patch, and determine if it's correct (since you seem to 
deal more with obscure Solaris bugs than the rest of us)? Thanks,

Dara

Why is the assertion absolete? And the ChangeLog entry is bogus:
--disable-multilib has always worked.

If by "assertion" you are referring to this sentence:

  When configuring on a Solaris 7 or later system that is running a kernel
  that supports only 32-bit binaries, one must configure with
  @option{--disable-multilib}, since we will not be able to build the
  64-bit target libraries.

It is obsolete because you can now build 64-bit target libraries even
on hosts that are running only 32-bit kernels.

OK, here's a revised ChangeLog entry:

2003-03-08  Paul Eggert  <eggert@twinsun.com>
 
        * gcc/doc/install.texi (Specific): --disable-multilib now is
        no longer necessary on Solaris 7 and later, unless Sun bug 4747851 is
        in effect; in that case, describe a workaround (for gcc) and a
        fix (for Solaris).

True, but some of the target libraries require *running* the resulting
64-bit executables, which still fails in such a configuration.  Besides, in
many cases hosts that don't support a 64-bit kernel (or where only a 32-bit
kernel is installed), the 64-bit system libraries are not installed either.

I'd suggest that unless we have positive reports that a full bootstrap for
both 32-bit and 64-bit multilibs works on a system with a 32-bit kernel,
but 64-bit system libraries installed, we keep that sentence.

	Rainer

Not a bug according to the documentation.

Suspended since it would become a bug if we changed our position regarding the
mandatory use of --disable-multilib on 32-bit kernels.
