This is a bug report for perl from Rob@desktop2,
generated with the help of perlbug 1.39 running under perl 5.12.1.


-----------------------------------------------------------------
[Please describe your issue here]

When building perl with the mingw64 x64 cross-compiler 'incpath', 'libpth', 
'ldflags', 'lddlflags' and 'ldflags_nolargefiles' values in Config.pm and 
Config_heavy.pl are not being set correctly because, with that compiler, the 
include and lib directories are not immediately below $(CCHOME). Here's a 
patch to win32/makefile.mk that addresses this issue:
