I think that would be sufficient in most situations. I think the
following will do the trick:

rule make-CYGWIN ( path )
{
return [ make-NT $(path) ] ;
}
rule native-CYGWIN ( path )
{
local result = $(path) ;
if [ regex.match "(^/.:)" : $(path) ] # win absolute
{
result = [ MATCH "^/?(.*)" : $(path) ] ; # remove leading '/'
}
return [ native-UNIX $(result) ] ;
}
