Compiler error is as follows:

/usr/include/libaio.h: In function `void io_set_callback(iocb*, void
(*)(io_context*, iocb*, long int, long int))':
/usr/include/libaio.h:142: invalid conversion from `void (*)(io_context*,
iocb*, long int, long int)' to `void*'

Version-Release number of selected component (if applicable):

Fix libaio.h so it will compile with c++ compilers

I tested the attached patch by installing the modified rpm, and performing a
build of a simple program which utilizes aio.  I then downgraded the library
version to taht shipped with RHEL 3 GA (0.3.96-3), and ran the program.  I
verified that the program worked as expected.

I believe Sybase is interested in this particular case, since they will be
building their applications against this version of the library, but deploying
on potentially older versions of RHEL.
