PTHREAD_MUTEX_ADAPTIVE_NP undefined in Gecko

[Riccardo Mottola]

Hi,

how is compilation of Gecko related browsers going on? I am trying to 
compile ArcticFox and I get this:

 3:43.44 
/home/multix/code/Arctic-Fox/nsprpub/pr/src/pthreads/ptsynch.c:60:48: 
error: ‘PTHREAD_MUTEX_ADAPTIVE_NP’ undeclared (first use in this 
function); did you mean ‘PTHREAD_MUTEX_FAST_NP’?
 3:43.44    60 |     rv = pthread_mutexattr_settype(&_pt_mattr, 
PTHREAD_MUTEX_ADAPTIVE_NP);
 3:43.44       | ^~~~~~~~~~~~~~~~~~~~~~~~~
 3:43.44       | PTHREAD_MUTEX_FAST_NP


The code is almost unchanged with current gecko, so I wonder if there 
were any workarounds attempted and/or upliftable patches for that.
