When generating .hid files from .src files, the script solenv/bin/mhids.pl
creates and runs a temporary program. The name of the program is constructed
from the basename of the .src file. Some .src files have names with strings
"setup", "patch", "update" or "install" in them (one even has two of them...).

Running programs with names that contain these strings (and other similar?)
cause an UAC dialog on Windows Vista and newer. That should be avoided, because
the pointless dialog pauses the build.

There is already a commented-out line in mhids.pl to handle this for "setup",
that needs to be uncommented, and additionally also the other magic strings handled.
