VMS: fix and generate the VMS build config config_h.com is a new file that generates a config.h file based on the curl_config.h.in file and a quick scan of the configure script. This is actually a generic procedure that is shared with other VMS packages. The existing pre-built config-vms.h had over 100 entries that were not correct and in some cases conflicted with the build options available in the build_vms.com. generate_config_vms_h_curl.com is a helper procedure to the config_h.com. It covers the cases that the generic config_h.com is not able to figure out, and accepts input from the build_vms.com procedure. build_curlbuild_h.com is a new file to generate the curlbuild.h file that Curl is now using when it is using a curl_config.h file. post-config-vms.h is a new file that is needed to provide VMS specific definitions, and most of them need to be set before the system header files are included. The VMS build procedure is fixed: 1. Fixed to link in the correct HP ssl library. 2. Fixed to detect if HP Kerberos is installed. 3. Fixed to detect if HP LDAP is installed. 4. Fixed to detect if gnv$libzshr is installed. 5. Simplified the input parameter parsing to not use a loop. 6. Warn that 64 bit pointer option support is not complete in comments. 7. Default to IEEE floating if platform supports it so resulting libcurl will be compatible with other open source projects on VMS. 8. Default to LARGEFILE if platform supports it. 9. Default to enable SSL, LDAP, Kerberos, libz if the libraries are present. 10. Build with exact case global symbols for libcurl. 11. Generate linker option file needed. 12. Compiler list option only commonly needed items. 13. fulllist option for those who really want it. 14. Create debug symbol file on Alpha, IA64.

$!
$! Curl like most open source products uses a variant of a config.h file.
$! Depending on the curl version, this could be config.h or curl_config.h.
$!
$! For GNV based builds, the configure script is run and that produces
$! a [curl_]config.h file. Configure scripts on VMS generally do not
$! know how to do everything, so there is also a [-.lib]config-vms.h file
$! that has VMS specific code that compensates for bugs in some of the
$! VMS shared images.
$!
$! This generates a [curl_]config.h file and also a config_vms.h file,
$! which is used to supplement that file. Note that the config_vms.h file
$! and the [.lib]config-vms.h file do two different tasks and that the
$! filenames are slightly different.
