John,

You have a conflict between components compiled to use LIBC
and those compiled to use MSVCRT.  One is the "static" C library
support, and the other is a seperate runtime C library DLL.  

My guess would be that your libjpeg and/or libpng are compiled
to use libc, and you have built GDAL the default way to use MSVCRT.

Basically, you can't practically mix object code built for different modes
with MSVC.  Either build everything the same way, or build libpng and
libjpeg as DLLs, and only link against the stub library instead of the full
static library.  

BTW, it is the /MD compiler option that select MSVCRT.  Leaving it
off should default to using LIBC.  I encourage use of MSVCRT though
it isn't strictly necessary.

Best regards,
