SqMod/vendor/POCO/Foundation/include/Poco/RWLock_WINCE.h
Sandu Liviu Catalin 4a6bfc086c Major plugin refactor and cleanup.
Switched to POCO library for unified platform/library interface.
Deprecated the external module API. It was creating more problems than solving.
Removed most built-in libraries in favor of system libraries for easier maintenance.
Cleaned and secured code with help from static analyzers.
