Subject: Lowercase configuration arguments on VMS
X-Git-Tag: OpenSSL_1_1_0-pre4~653
X-Git-Url: https://git.openssl.org/?p=openssl.git;a=commitdiff_plain;h=7c55e22c6976d6d19cb6c2340c2f22316546bfca

Lowercase configuration arguments on VMS

Depending on user preferences, Configure might get something like
--PREFIX=blah just as well as --prefix=blah, or "SHARED" just as well
as "shared".  On VMS, let's therefore lowercase at least the portion
of the argument before a possible equal sign.

For good measure, we lowercase the arguments to be checked in
config.com as well.  The original argument is sent on to Configure,
however.
