How To Compile

If you're getting huge binaries, probably your makefiles have the -g in
CFLAGS.
+VMS
+===
+ (The VMS section is in whole contributed by the friendly Nico Baggus)
+
+ This is the first attempt at porting cURL to VMS.
+
+ Curl seems to work with FTP & HTTP other protocols are not tested. (the
+ perl http/ftp testing server supplied as testing too cannot work on VMS
+ because vms has no concept of fork(). [ I tried to give it a whack, but
+ thats of no use.
+
+ SSL stuff has not been ported.
+
+ Telnet has about the same issues as for Win32. When the changes for Win32
+ are clear maybe they'l work for VMS too. The basic problem is that select
+ ONLY works for sockets.
+
+ Marked instances of fopen/[f]stat that might become a problem, especially
+ for non stream files. In this regard, the files opened for writing will be
+ created stream/lf and will thus be safe. Just keep in mind that non-binary
+ read/wring from/to files will have a records size limit of 32767 bytes
+ imposed.
+
+ Stat to get the size of the files is again only safe for stream files &
+ fixed record files without implied CC.
+
+ -- My guess is that only allowing access to stream files is the quickest
+ way to get around the most issues. Therefore all files need to to be
+ checked to be sure they will be stream/lf before processing them. This is
+ the easiest way out, I know. The reason for this is that code that needs to
+ report the filesize will become a pain in the ass otherwise.
+
+ Exit status.... Well we needed something done here,
+
+ VMS has a structured exist status:
+ | 3 | 2 | 1 | 0|
+ |1098|765432109876|5432109876543|210|
+ +----+------------+-------------+---+
+ |Ctrl| Facility | Error code |sev|
+ +----+------------+-------------+---+
+
+ With the Ctrl-bits an application can tell if part or the whole message has
+ allready been printed from the program, DCL doesn't need to print it again.
+
+ Facility - basicaly the program ID. A code assigned to the program
+ the name can be fetched from external or internal message libraries
+ Errorcode - the errodes assigned by the application
+ Sev. - severity: Even = error, off = non error
+ 0 = Warning
+ 1 = Success
+ 2 = Error
+ 3 = Information
+ 4 = Fatal
+ <5-7> reserved.
+
+ This all presents itself with:
+ %<FACILITY>-<SeV>-<Errorname>, <Error message>
+
+ See also the src/curlmsg.msg file, it has the source for the messages In
+ src/main.c a section is devoted to message status values, the globalvalues
+ create symbols with certain values, referenced from a compiled message
+ file. Have all exit function use a exit status derived from a translation
+ table with the compiled message codes.
+
+ This was all compiled with:
+
+ Compaq C V6.2-003 on OpenVMS Alpha V7.1-1H2
+
+ So far for porting notes as of:
