Please try the attached patch.
Please also tell us identification of your environment:
- Is it "VMS"? Or "OpenVMS"?
- Which version? You're talking about 7.3 here, 8.2 there, 8.4 then...
- [Not for this patch, but for other ones.] What's the best C preprocessor
conditionals for your environment? According to predef.sf.net, I guess
it's __DECC for the compiler and __VMS for the operating system?
Conditionalized with __VMS_VER >= 82000000 or __VMS_VER >= 84000000 ?
