I installed http://ftp.gnu.org/gnu/binutils/binutils-2.19.tar.bz2 and I am aware of the ./configure arguments usually used on OpenSolaris. The "Bug": The file gcc/config/i386/sol2-10.h uses "USE_GAS" in an "#ifdef" (on line 27) but since "USE_GAS" does not get defined the "#else" is taken. That results in "-xarch=" being used in an argument for "as". The file gcc/config/i386/sol2-10.h says: /* binutils' GNU as understands --32 and --64, but the native Solaris assembler requires -xarch=generic or -xarch=generic64 instead. */ The OpenSolaris (2008.11) man page for "as" (dated 2004-10-28) says: Target SPARC options: [-Av6|-Av7|-Av8|-Asparclet|-Asparclite -Av8plus|-Av8plusa|-Av9|-Av9a] [-xarch=v8plus|-xarch=v8plusa] [-bump] [-32|-64] Target i386 options: [--32|--64] [-n] There seem to be a few incorrect assumptions that have come together to cause us to make assumptions about what was originally intended and how best to fix it. The file "gcc/config/i386/sol2-10.h" uses the term "native Solaris assembler" but it is very unlikely that someone would use Sun Studio's assembler with "xgcc", they might use "Sun's supplied GNU as" (if that is what is meant by the term "native Solaris assembler") with xgcc (but not if they just finished installing binutils 2.19) but "as" does not accept "-xarch" (for the x86 platform). The term "native Solaris assembler" is confusing since it is common to use "GNU as" for GNU programs (especially xgcc), perhaps it is a mis-thought confusion of the so-called "native Solaris linker" which is Sun's modified version of GNU's "ld". Sun has a recommended linker to use for linking but the assembler (or compiler) is not so restricted. The "#ifdef" seems only helpful for the "sparc" platform and not useful for the "x86" the author seems willing to set "-xarch=generic" and "-xarch=generic64" but ought to use "--32" or "--64" instead.
