You cannot expect that to work. You're trying to bootstrap a 32-bit compiler
(sparc-sun-solaris2.8) with a 64-bit compiler (cc -xarch=v9). Unsupported.
You need either to bootstrap the 64-bit compiler (sparc64-sun-solaris2.8)
CC="cc -xarch=v9" $srcdir/configure sparc64-sun-solaris2.8; gmake bootstrap
or build a cross-compiler from sparc64-sun-solaris2.8 to sparc-sun-solaris2.8
CC="cc -xarch=v9" $srcdir/configure --host=sparc64-sun-solaris2.8
--target=sparc-sun-solaris2.8 ; gmake
Andrew, please redirect these kinds of PRs to me. Thanks in advance.
