I took the liberty of running try builds with your patch on the Solaris
builders:

  https://gdb-build.sergiodj.net/builders/Solaris11-amd64-m64/builds/410
  https://gdb-build.sergiodj.net/builders/Solaris11-sparcv9-m64/builds/408

Unfortunately the build still fails with:

  ../../binutils-gdb/gdb/sol-thread.c: In member function ‘virtual ptid_t sol_thread_target::wait(ptid_t, target_waitstatus*, int)’:
  ../../binutils-gdb/gdb/sol-thread.c:465:2: error: expected ‘)’ before ‘{’ token
    {
    ^
  ../../binutils-gdb/gdb/sol-thread.c:470:5: error: expected primary-expression before ‘}’ token
       }
       ^

BTW, it's possible to run try builds on specific builders by using the
"-b" option with "buildbot try".  E.g.:

  buildbot try -b Solaris11-amd64-m64 -b Solaris11-sparcv9-m64

Thanks,
