Fix PR1606:

Browse Source 
The AC_CHECK_HEADER macro was used instead of AC_CHECK_HEADERS. The former does
not automatically add a #define to the configure variables while the latter
does. Consequently, the HAVE_PTHREAD_H symbol was not defined which caused the
Mutex.cpp file to compile to an empty implementation.
