* Defining _WIN32_WINNT here in e_os.h implies certain "discipline."
* Most notably we ought to check for availability of each specific
* routine with GetProcAddress() and/or quard NT-specific calls with
* GetVersion() < 0x80000000. One can argue that in latter "or" case
* we ought to /DELAYLOAD some .DLLs in order to protect ourselves
* against run-time link errors. This doesn't seem to be necessary,
* because it turned out that already Windows 95, first non-NT Win32
* implementation, is equipped with at least NT 3.51 stubs, dummy
* routines with same name, but which do nothing. Meaning that it's
* apparently appropriate to guard generic NT calls with GetVersion
* alone, while NT 4.0 and above calls ought to be additionally
* checked upon with GetProcAddress.
