I'm new to the list so forgive me if this has come up before.

Problem definition:

This only applies to win32 builds of libtiff. I am working with version 3.6.0-beta.

Since the makefile.vc doesn't define any calling convention, cdecl is used as a default. I prefer stddecl and use it as the default when building my projects. When I link to libtiff, the linker can't match up any of the TIFFXxx functions because the library and the application where built using two different calling conventions.

Solution:

To tiffio.h I added a TIFFDECL define to explicitly use cdecl for win32 builds. I used TIFFDECL in every function pointer typedef and function prototype.

I would like to submit this to the libtiff project so everyone else can have it, but have no idea how to go about this.
