-Sun patch 107058-01 (1999-01-13) for Solaris 7/SPARC 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.
-
-Here are some workarounds to this problem:
-@itemize @bullet
-@item
-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 7-based hosts, so you may have to
-back it out.
-
-@item
-Copy the original, unpatched Solaris 7
-@command{/usr/ccs/bin/as} into
-@command{/usr/local/libexec/gcc/sparc-sun-solaris2.7/3.4/as},
-adjusting the latter name to fit your local conventions and software
-version numbers.
-
-@item
-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. The current (as of 2004-05-23) revision is -24, and is included in
