Thank you for your response.


I tried to build "realtime" tests with recent git "ltp-c23c351.tar.gz".

Build succeeded in RHEL5.5-x86 system.

But build failed in RHEL4.8-x86/x86_64/ia64 systems:

------------

The error of the "async_handler.c" by "__sync_add_and_fetch" until yesterday 
was solved.
However, a new failure about mutex occurs in another function.

I am investigating about it.
Perhaps.. perhaps, mutex is supported after kernel version 2.6.16, I think.


This is just a quick note to let you know.


Thank you--
