with-timeout macro not available at compile time, XEmacs

Someone (probably with the surname Welinder) reported bugginess with current tip VM when byte-compiled, and mentioned the following byte-compile warning in the bug report:

While compiling vm-imap-make-session in file
/home/welinder/vm/src/lisp/vm-imap.el:
  ** (or vm-imap-server-timeout 1000) is a malformed function
  ** (or vm-imap-server-timeout 1000) is a malformed function
  ** (or vm-imap-server-timeout 1000) is a malformed function
  ** (or vm-imap-server-timeout 1000) is a malformed function

This warning is because the #'with-timeout macro was not available at compile time, and as such evaluation of its arguments was broken and incorrect. The following patch eliminates the warning for me, though I haven't tested more intensively:
