How do I fix "gcc: winrespp.rc: No such file or directory" during compiling PAR::Packer on Cygwin? - perl

Question

I have tried to install PAR::Packer in Cygwin for Windows on a 32 bit machine, so I executed cpan pp.
I am facing the following problem.
gcc-4 -c -DPERL_USE_SAFE_PUTENV -U__STRICT_ANSI__ -g -fno-strict-aliasing -pipe -fstack-protector -I/usr/local/include -I/usr/lib/perl5/5.14/i686-cygwin-threads-64int/CORE -DPARL_EXE=\parl.exe\ -O3 main.c windres -F pei-i386 -i winres\pp.rc -o winres\pp.res
gcc: winrespp.rc: No such file or directory
gcc: warning: '-x c' after last input file has no effect
gcc: no input files
windres: preprocessing failed.

The problem is in myldr/Makefile.PL:
$pre_res = qq(winres\\pp.res);
$rt_cmd = qq(windres -F pei-i386 -i winres\\pp.rc -o $pre_res);
$res_cmd = qq(windres -o ppresource.coff $pre_res);
$res_section = $res;
and, later,
$res_section:
$rt_cmd
$res_cmd
Under Cygwin's bash, winres\pp.rc would be interpreted as winrespp.rc instead of winres/pp.rc. The correct way would be
$pre_res = catfile(winres => 'pp.res');
$rt_cmd = join ' ' => qw(windres -F pei-i386 -i), catfile(winres => 'pp.rc'), '-o', $pre_res;
etc.
