Re: build of 2021/03/07 -current fails because of pthread_types.h (without MKLLVM!)

So, the clue is in the last two "notes" from the compiler:

/build/woods/b2/current-amd64-destdir/usr/include/pthread_types.h:170:8: note: '__pthread_cond_st' is not literal because:
  170 | struct __pthread_cond_st {
      |        ^~~~~~~~~~~~~~~~~
/build/woods/b2/current-amd64-destdir/usr/include/pthread_types.h:175:17: note:   non-static data member '__pthread_cond_st::ptc_waiters' has volatile type
  175 |  void *volatile ptc_waiters;
      |                 ^~~~~~~~~~~


These lead me to pthread_types.h, and to the apparent change that may
have introduced the fault (revision 1.25 of pthread_types.h), which
after looking at the full set of changes in 1.25 lead me to find the
definition of __pthread_volatile, and that allowed me to read the
comment about this definition and that suggested the following fix,
which at least allows the compile to continue.  I hate C++ and I hate
debugging C++, but here at least I'm grateful someone had already
figured out how to solve the problem and I only had to apply it in one
more place.

If all goes well I should be able to test the build under Xen in the
next few hours.
