Build fail on gthr-simple.h targets (Re: AsyncI/O patch committed)

[David Edelsohn]

Thomas,

Correct, the proposed patch does not fix the build failure on AIX.

Please see the information on the GCC Compile Farm wiki page for
instructions to bootstrap on gcc119.
https://gcc.gnu.org/wiki/CompileFarm#Projects_Ideas - at the bottom of
Project ideas.

Thanks, David
