Thanks, the following rules actually trigger the dependencies:
(string)
$(lpfx)wcwidth.$(oext): wcwidth.c ambiguous.t combining.t wide.t
(ctype)
$(lpfx)categories.$(oext): categories.c categories.t
$(lpfx)towctrans_l.$(oext): towctrans_l.c caseconv.t

but they cause obscure compilation errors:
In file included from /usr/include/sys/config.h:234:0,
                 from /usr/include/_ansi.h:11,
                 from ../../../.././newlib/libc/string/wcwidth.c:91:
/usr/include/cygwin/config.h:40:29: fatal error: ../tlsoffsets64.h: No 
such file or directory
 #include "../tlsoffsets64.h"
                             ^
(Maybe it's just one of these volatile errors that occasionally occur 
when building cygwin?)
I'll try on another system, or else just provide the patch for Brian 
(who requested the implicit approach) to work this out...
