<<You probably shouldn't deploy any of them. msvcrt.dll is a system library
and should be installed/upgraded as a group with the other system
libraries that are dependant upon it. Firebird only includes it to
support the increasingly rare cases where a system has an older version
of the library.>>

But the version that comes with Firebird is older than all the other ones I
have on my system.
