+may vary if you use a combination of the GNU tools and the Sun tools: while

+You can obtain a working version by checking out the binutils-2_15-branch

Sun bug 4296832 turns up when compiling X11 headers with GCC 2.95 or
newer: @command{g++} will complain that types are missing. These headers assume
108377-20 for Intel), and Solaris 8 (108652-24 or newer for SPARC,
108653-22 for Intel) that fix this bug.
+Sun bug 4927647 sometimes causes random spurious testsuite failures
+related to missing diagnostic output. This bug doesn't affect GCC
+itself, rather it is a kernel bug triggered by the @command{expect}
+program which is used only by the GCC testsuite driver. When the bug
+causes the @command{expect} program to miss anticipated output, extra
+testsuite failures appear.
+
+There are patches for Solaris 8 (117350-12 or newer for SPARC,
+117351-12 or newer for Intel) and Solaris 9 (117171-11 or newer for
+SPARC, 117172-11 or newer for Intel) that address this problem.

assembler, this change apparently runs afoul of Sun bug 4910101, for
which (as of 2004-05-23) there is no fix. A symptom of the problem is
that you cannot compile C++ programs like @command{groff} 1.19.1
-without getting messages like @samp{ld: warning: relocation error:
-R_SPARC_UA32 @dots{} external symbolic relocation against
-non-allocatable section .debug_info; cannot be processed at runtime:
-relocation ignored}. To work around this problem, compile with
-@option{-gstabs+} instead of plain @option{-g}.
