Bug 695882: ensure function protypes are available
|
|
|
|
There are some special defines on Linux to include prototypes for pread, pwrite
|
|
and pthread_mutexattr_settype: add these to our "unistd_.h" header.
|
|
|
|
Also, tweak the the configure script to check for prototypes as well as just
|
|
successful linking before including the code that uses those functions
|
|
|
|
No cluster differences
