[asterisk-dev] The check for pthread_rwlock_timedrdlock

[Olle E. Johansson]

Tilghman,
Thanks for fixing this. However, you might want to read this snippet  
on how to check for these POSIX functions:
http://lists.apple.com/archives/Unix-porting/2008/Jan/msg00014.html

"Things get a little confusing sometimes because people tend to use  
GNU configure instead of using the feature test macros defined in  
<unistd.h>, like they are supposed to, and because there is no forward  
index mapping option groups to each interface. As a result, you end up  
having to look up the interface on a case by case basis to see what  
option group it falls under, and then you have to look up the option  
group by its long name to try to find the constant in <unistd.h>. You  
can also have non-compliant interfaces with the same names accidently  
found by configure, if it uses the linker to test for the existence of  
the symbol name in libc, rather than testing for the feature using the  
POSIX feature-test macro."

It' might be an improvement for the future.
