    NAME:       FtpdAssert

    SYNOPSIS:   Called if an assertion fails.  Displays the failed
                assertion, file name, and line number.  Gives the
                user the opportunity to ignore the assertion or
                break into the debugger.

    ENTRY:      pAssertion - The text of the failed expression.

                pFileName - The containing source file.

                nLineNumber - The guilty line number.
