89 * Defining _WIN32_WINNT here in e_os.h implies certain "discipline."
90 * Most notably we ought to check for availability of each specific
91 * routine that was introduced after denoted _WIN32_WINNT with
92 * GetProcAddress(). Normally newer functions are masked with higher
93 * _WIN32_WINNT in SDK headers. So that if you wish to use them in
94 * some module, you'd need to override _WIN32_WINNT definition in
95 * the target module in order to "reach for" prototypes, but replace
96 * calls to new functions with indirect calls. Alternatively it
97 * might be possible to achieve the goal by /DELAYLOAD-ing .DLLs
98 * and check for current OS version instead.

104 * Just like defining _WIN32_WINNT including winsock2.h implies
105 * certain "discipline" for maintaining [broad] binary compatibility.
106 * As long as structures are invariant among Winsock versions,
107 * it's sufficient to check for specific Winsock2 API availability
108 * at run-time [DSO_global_lookup is recommended]...

215 We need to do this since VMS has the following coding on status codes:
217 Bits 0-2: status type: 0 = warning, 1 = success, 2 = error, 3 = info ...
218 The important thing to know is that odd numbers are considered
219 good, while even ones are considered errors.
220 Bits 3-15: actual status number
221 Bits 16-27: facility number. 0 is considered "unknown"
222 Bits 28-31: control bits. If bit 28 is set, the shell won't try to
223 output the message (which, for random codes, just looks ugly)
225 So, what we do here is to change 0 to 1 to get the default success status,
226 and everything else is shifted up to fit into the status number field, and
227 the status is tagged as an error, which is what is wanted here.
229 Finally, we add the VMS C facility code 0x35a000, because there are some
230 programs, such as Perl, that will reinterpret the code back to something
231 POSIX. 'man perlvms' explains it further.
233 NOTE: the perlvms manual wants to turn all codes 2 to 255 into success
234 codes (status type = 1). I couldn't disagree more. Fortunately, the
235 status type doesn't seem to bother Perl.
