That notation means that "file" is a utility documented in section 1 of the 
man
pages.  

$ man file | head
FILE(1)                   BSD General Commands Manual                  FILE(1)

NAME
     file - determine file type

SYNOPSIS
     file [-bchiklLNnprsvz0] [--apple] [--mime-encoding] [--mime-type]
          [-e testname] [-F separator] [-f namefile] [-m magicfiles] file ...
     file -C [-m magicfiles]
     file [--help]

Sometimes different sections of the manual have the same title.  The
parenthetical number avoids ambiguity and is an immediate hint we're talking
about a standard utility.

Apparently shared libraries are named .DLL in cygwin.  The .a files on my 
system
are static libraries, e.g.: 

$ file /usr/lib/libticw.*
/usr/lib/libticw.a:     current ar archive
/usr/lib/libticw.dll.a: current ar archive
/usr/lib/libticw.la:    libtool library file

HTH.
