+ Beefed up and fixed -reqpkg feature:
+ Possible to pass multiple alternate pkg names:
-reqpkg=cairo|cairo2|cairo.h
+ Possible to attach header name, in which case it
will automatically satify the -reqheader= parameter
with same header name, if it exists. Headers without
extension can be specified as 'header.'
! Fixed to use case-insensitive lookup in header list
on non-*nix systems.
+ Added -info messages regarding pkg detection.
! Fixed parsing of -l/-L/-I parameters in pkg detection
code.
