I'm using haskell-gi-base-0.21.2. It compiles fine under Linux, but when I try to compile it on Windows using MinGW64 I get an error message (see attached log file):

\hsgclosure.c:29:36:
error: 'PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP' undeclared here (not in a function); did you mean 'PTHREAD_RECURSIVE_MUTEX_INITIALIZER'?
