re PR libgcj/30513 (Bootstrap failure with libgcj on sparc-sun-solaris2.10)
2007-01-27 Andreas Tobler <a.tobler@schweiz.org>
PR libgcj/30513
* configure.host: Add forgottten sysdep_dir to sparc. Add a flag to
libgcj_flags to undefine 'sun' at compile time.
* sysdep/sparc/locks.h (read_barrier): New functions for 32 and 64 bit
Sparc.
(write_barrier): Likewise.
