In packages/vms/generate_config_vms_h_curl.com:

$write cvh "#ifndef __VAX"
$write cvh "#ifdef CURL_DISABLE_NTLM"
$write cvh "#undef CURL_DISABLE_NTLM"
$write cvh "#endif"
$write cvh "#else"
$! NTLM needs long long or int64 support, missing from DECC C.
$write cvh "#ifdef __DECC
$write cvh "#ifndef CURL_DISABLE_NTLM"
$write cvh "#define CURL_DISABLE_NTLM 1"
$write cvh "#endif"
$write cvh "#endif"
$write cvh "#endif"

This is what I had to add for VAX to compile lib/curl_ntlm_core.c for
the daily build back in the November/December time frame where I
submitted the patch.

I have not checked if it is still needed for 7.40.0.

I did not have to do anything for SMB.

VMS does not typically run the configure script. While it is possible
with GNV (GNU on VMS) for Alpha and Itanium, not enough of GNV works on
VAX to use it.

On VMS, configure is done by two DCL scripts. The first script,
lib/curl_ntlm_core.c, is custom written to know what VMS can not figure
out from reading the config.h.in file to generate a config_vms.h

The second script, config_h.com reads the config.h.in file and then
scans the header files, shared libraries, and the configure script to
build the curl_config.h with includes the config_vms.h as a last step.
The config_h.com is shared with multiple projects.

The file that processes config.h.in scans the configure script to guess
the defaults for symbols that are only defined in the configure script
and takes the first value assigned to that symbol. For curl that
usually defaults to enabling the build option, so the first script has
to know which to override for a platform.

On my Alpha systems, the DCL scripts run more than an order of magnitude
faster than the configure script, so that is what is normally used.
