  Gnulib module: pthread-rwlock
  
  Portability problems fixed by Gnulib:

  This function is missing on some platforms:
  macOS 11.1, FreeBSD 5.2.1, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, HP-UX 11, IRIX 6.5, Solaris 9, Cygwin 1.7.x, mingw, MSVC 14, Android 4.3.
  But the provided replacement is just a dummy on some of these platforms:
  Minix 3.1.8.

  Portability problems not fixed by Gnulib:
  @itemize
  @item
  This function prefers readers to writers (meaning, when this function is
  called on an rwlock that is already taken by one or more readers, and
  another writer is already waiting to take it, this function may return
  successfully immediately) -- a behaviour that may lead to writer starvation --
  on some platforms:
  glibc 2.28.
  @end itemize
