update to status of Solaris 7 dynamic linker bug with GCC

[Paul Eggert]

Sun just reported to me some more details about the status of the
Solaris 7 dynamic linker bug exposed by Sun patch 107058-01 and GCC.
Here's a proposed update to GCC's install/specific.html file that
reflects the current status as I know it.  A similar update needs to
be made to install/SPECIFIC.  (I don't see offhand the relationship
between those two files -- surely they're not both maintained by
hand?)

*** install/specific.html	Mon Aug 16 02:16:48 1999
--- /tmp/specific.html	Wed Oct  6 14:58:07 1999
*************** if you initially built it with gcc-2.7.2
*** 427,437 ****
  
  <p>Sun patch 107058-01 (1999-01-13) for SPARC Solaris 7 triggers a bug in
  the dynamic linker.  This problem (Sun bug 4210064) affects GCC 2.8
! and later, including all EGCS releases.  To avoid this problem, do not
! install Sun patch 107058-01 until after Sun releases a patch for bug
! 4210064.  Sun has a fix for this bug but (as of 1999-06-24) has not
! yet released it as a patch.</p>

  <p>Sun patch 107058-01 (1999-01-13) for SPARC Solaris 7 triggers a bug in
  the dynamic linker.  This problem (Sun bug 4210064) affects GCC 2.8
! and later, including all EGCS releases.  Sun formerly recommended
! 107058-01 for all Solaris 7 users, but around 1999-09-01 it started to
! recommend it only for people who use Sun's compilers.
  
+ <p>Here are some workarounds to this problem:
+ 
+ <ul>
+   <li>Do not install Sun patch 107058-01 until after Sun releases a
+   complete patch for bug 4210064.  This is the simplest course to take,
+   unless you must also use Sun's C compiler.  Unfortunately 107058-01
+   is preinstalled on some new Solaris-based hosts, so you may have to
+   back it out.
+ 
+   <li>Copy the original, unpatched Solaris 7
+   <code>/usr/ccs/bin/as</code> into
+   <code>/usr/local/lib/gcc-lib/sparc-sun-solaris2.7/2.95.1/as</code>,
+   adjusting the latter name to fit your local conventions and software
+   version numbers.
+ 
+   <li>Install Sun patch 106950-03 (1999-05-25) or later.  Nobody with
+   both 107058-01 and 106950-03 installed has reported the bug with GCC
+   and Sun's dynamic linker.  This last course of action is riskiest,
+   for two reasons.  First, you must install 106950 on all hosts that
+   run code generated by GCC; it doesn't suffice to install it only on
+   the hosts that run GCC itself.  Second, Sun says that 106950-03 is
+   only a partial fix for bug 4210064, but Sun doesn't know whether the
+   partial fix is adequate for GCC.  Revision -08 or later should fix
+   the bug, but (as of 1999-10-06) it is still being tested.
+ </ul>
