Patch to fix the problem

Haven't done much testing but the code passed visual inspection.

change libaio to use syscall(2)

This patch gets rid of the inline assembler and changes it to use syscall(2). 
I've also added the -fpic as suggested by Uli.	Uli, does this fix the problem
equally as well?

Comment 3 Ulrich Drepper 2004-02-25 06:51:37 UTC
The patch looks OK.  Using syscall() is a little bit less efficient
but the costs vanish compared to the syscall cost itself.  I haven't
tested the patch but if it builds on all archs and the test using
readelf described in the report everything should be fine.

Comment 4 Ulrich Drepper 2004-08-26 07:42:25 UTC
The second patch is in the current release (0.3.99).
