Redefinition of PTHREAD_MUTEX_xxx

[Joel Sherrill]

Hi,

I noticed something I think is redundant
and useless in sys/types.h.

There is a block of code conditional
on XMK and RTEMS which defines
PTHREAD_MUTEX_NORMAL, PTHREAD_MUTEX_RECURSIVE,
PTHREAD_MUTEX_ERRORCHECK, and
#define PTHREAD_MUTEX_DEFAULT.

Later there is a block of code conditional
on _UNIX98_THREAD_MUTEX_ATTRIBUTES which
redefines them different values.

As best I can tell, both RTEMS and XMK
define _UNIX98_THREAD_MUTEX_ATTRIBUTES
so trip both blocks of code.

The first has comments on the constants
while the second (UNIX98) block does not.

With confirmation that both XMK and
RTEMS trip both blocks and the first is
useless, I propose the following:

+ move the comments from the first
   to the second block
+ remove the first block

Can I get a doublecheck on the analysis
and then I will submit a patch.

Thanks.
