Perl seems to understand both ways as absolute paths:

$ perl -e 'use File::Spec; print File::Spec->rel2abs("c:/temp")'
c:/temp

$ perl -e 'use File::Spec; print File::Spec->rel2abs("/cygdrive/c/temp")'
/cygdrive/bin/perl

$ which perl
/usr/bin/perl

$ perl --version | head -2 | tail -1
This is perl 5, version 14, subversion 2 (v5.14.2) built for cygwin-thread-multi-64int
