[Pvfs2-developers] Can _GNU_SOURCE be defined?

[Scott Atchley]

Hi all,

I would like to use Pthread read/write locks. It seems that it  
depends on __USE_UNIX98 being defined, which depends on _XOPEN_SOURCE  
being defined, which depends on _GNU_SOURCE being defined.

Would this break anything? If not, should I do it locally in my  
header file or should it come from PVFS?

Thanks,

Scott
