Hi all,

I'm having problems with compiling MS3.7 under Win32. As far as I can tell,
I have all the libraries built correctly and they are not conflicting
versions. I am using GD2.0.7gif in order to get 24-bit rendering, and have
enabled WFS and WMS support using libcurl.

Everything compiles fine, but at the link stage I get errors about a
conflict between LIBC.lib and MSVCRT.lib (see below). I've seen messages
before about multi-threaded versions of freetype causing this problem, but I
am definitely linking to the single-threaded version. Are there any other
libraries that could be causing such a problem?

I'm welcome to suggestions! I would ask if anyone has a pre-built
executable, but a 3.7 exe with WMS, WFS, 24-bit, GDAL, OGR AND ORACLE
SPATIAL support is probably asking a bit much..... ;-)

Cheers in advance,

Matt.
