#665 Support for OpenVMS IA64

[zinser]

Hello,

while building NEdit 5.5 on OpenVMS IA64 V8.3-1H1 with a recent C compiler,
I encountered the following problems:

cc/prefix=all/define=(USE_ACCESS)/include=[-.xlt] TEXTDRAG.C

if (modPos + nDeleted > *modRangeEnd) {
................................^
%CC-W-UNINIT1, The scalar variable "bufModRangeEnd", declared in "BlockDragSelec
tion", is fetched but not initialized. Detected when this routine was inlined a
t line number 247 in file PUBLIC$ROOT:[XTOOLS.XUTIL.NEDIT.SOURCE]TEXTDRAG.C;10.
And there may
be other such fetches of this variable that have not been reported in this compi
lation.
at line number 512 in file PUBLIC$ROOT:[XTOOLS.XUTIL.NEDIT.SOURCE]TEXTDRAG.C;10

*unmodRangeEnd += modPos + nDeleted - *modRangeEnd;
............^
%CC-W-UNINIT1, The scalar variable "tempModRangeEnd", declared in "BlockDragSele

---> rint is not available on the oldest VMS plattform (VAX), but on Alpha and
Itanium. Code in vmsUtils.c checked for !Alpha as VAX, which is incorrect once
Itanium is added to the mix. Change code to explicitly check for VAX as in
attached patch.

This is all on top of the changes reported in issue 1395689.

What are the chances of a new release of NEdit? It is still my favorite editor
on both OpenVMS and Linux :-)

Greetings, Martin
