I don't think there's anything wrong with easy.c - but beware that 'easy.c' is
made (by perl.exe) from 'easy.xs', and that much of what you are trying to
change is put there by your 'perl.exe' because it "knows what's correct".

There are a very large number of include files that will be requested by
almost any piece of C code, including those in the perl directory and those
'standard' headers that should be provided by your system (or compiler).

Rather than copying them all over to the Curl::easy directory, you should be
able to tell your compiler where to find them all itself.

The headers for perl itself seemt to be already correct in your Makefile, as
the 'cl' command you showed previously had

"-IC:\Perl\lib\CORE"

as one of its options. The other headers you mentioned (arpa/inet.h etc.)
would be considered 'standard' system headers on unix, but I don't know where
they might be on your system. I imagine they are under the Visual C
directories somewhere, in which case I would have expected 'cl' to be able to
find them itself.

I would give up copying everything, and look for a simpler root cause -
perhaps your compiler isn't quite configured properly, or it's settings are
different from the ones used when perl.exe was made.

These are just warnings, and can be ignored. I will note them for attention in
a future release.

When compiling, your compiler can't find the headers, and this is fixed by
telling it where to look with -I . Now your are linking, and your linker
can't find the appropriate libraries (perl.dll or whatever). You'll have to
tell the linker where to look for libraries using the -L option.

Normally the -I and -L options are put into the Makefile by perl when you run
'perl Makefile.PL', but the values you need are different from the ones perl
"knows", which are the ones used by Active State when they made perl.exe.

You seem to need to change both the LIBS and INC options, either by editting
Makefile.PL, or using 'perl Makefile.PL LIBS=c:\blah\blah INC=c:\blahblah'.

I don't know where anything is on your machine, so I can't tell you what
values you need to use though...
