[PATCH] doxygen patch for apr_os_thread_equal()

[Stefan Ruppert]

Hi all,

attached you will find a small doxygen patch for the 
apr_os_thread_equal() function. I looked for the correct return value 
and needed to consult the pthread_equal() man page... ;-)

Also the generated documentation on the APR web-site seems outdated. APR 
1.4 was generated on Feb 2010, the trunk on Jul 2009!!!

Can someone generate a current snapshot? Is it possible to do this 
automatically??

Regards,
Stefan
