Strawberry's gcc-generated libs won't talk to Sybase's client libs, so I am back to compiling using VC2012, full edition.

-perl 5.18.1

-I'm on a Win7 machine, 64 bit.

-I'm using a 64 bit compiler:

`U:\perlbuild\tools>cl
Microsoft (R) C/C++ Optimizing Compiler Version 17.00.50727.1 for x64
Copyright (C) Microsoft Corporation. All rights reserved.
usage: cl [ option... ] filename... [ /link linkoption... ]
U:\perlbuild\tools>
`

I have read the README.win32 and set the appropriate values in the win32\Makefile file. But when I compile, I get lots of size mismatch warnings. Here is the unique set:

`conversion from 'IV' to 'DWORD', possible loss of data

I'm thinking I'm missing a flag setting somewhere. Here is a sample compile command:

` cl -c -nologo -GF -W3 -I..\lib\CORE -I.\include -I. -I.. -DWIN32 -
+D_CONSOLE -DNO_STRICT -DWIN64 -DCONSERVATIVE -D_CRT_SECURE_NO_DEPRECA
+TE -D_CRT_NONSTDC_NO_DEPRECATE -DPERLDLL -DPERL_CORE -O1 -MD -Zi -D
+NDEBUG -GL -fp:precise -DPERL_IS_MINIPERL -Fo.\mini\win32thread.obj w
+in32thread.c
`

I'll keep testing, but if someone has done this and would like to point out if I am missing a flag somewhere, I'd appreciate it.

Thanks
