Re: Build Failure for 2.96 (20000731) on sparc-sun-sunos4.1.4

[Manfred Hollstein <manfredh at redhat dot com>]

I believe this should be fixed by the patch, Alexandre sent yesterday:

  From: Alexandre Oliva <aoliva@redhat.com>
  Sender: aoliva@guarana.lsd.ic.unicamp.br
  Organization: GCC Team, Red Hat
  To: Manfred Hollstein <manfred.h@gmx.net>
  Cc: gcc-patches@gcc.gnu.org
  Subject: Re: Accept blanks as language separators
  Date: 01 Aug 2000 13:56:24 -0300

  Indeed.  Here's a patch that presumably handles LANGUAGES correctly.
  Ok to install, if it works?  (I haven't tested it, because I've got to
  leave in a couple of minutes; I'd appreciate if someone else could
  give it a try while I'm away)

  >from  Alexandre Oliva  <aoliva@redhat.com>
	* configure.in (CHILL_FOR_TARGET, CXX_FOR_TARGET): Convert blanks to
	commas in $LANGUAGES.

BTW, Jason Merrill approved it in the meantime, so it may have been
checked in already.

Cheers, manfred
