Possible Compilation issue: missing header file
-----------------------------------------------

The header file <stdint.h> is included in 'yices.h' so it's required
to compile and link with the yices library. That's not a problem with
GCC as all versions of GCC I've seen follow the C99 standard (more or
less) and they all include <stdint.h>.

Unfortunately, Microsoft Visual Studio does not even try to
approximate C99, and some versions of Visual Studio do not have
<stdint.h>

The simplest workaround for using 'yices.h' on a system that does not
have <stdint.h> is to get an open-source replacement:

   'msinttypes' at http://code.google.com/p/msinttypes
   'pstdint.h' at http://www.azillionmonkeys.com/qed/


For compilation with Visual Studio, just copy one of the open-source
stdint.h into the include directory.




DLL import/export directives
----------------------------

On cyginw, mingw, or Windows native, we distribute the Yices library
as a DLL. For proper compilation and link with this DLL, all functions
and variables in 'yices.h' must be declared with '__declspec(dllimport)'.


But when we build the library and compile yices itself, all the
functions must be exported (i.e., declared with '__declsepc(dllexport)').

Solution for now:
- all declarations in 'yices.h' are decorated with '__YICES_DLLSPEC__'
- by default 'yices.h' defines __YICES_DLLSPEC__ to __declspec(dllimport)
- but 'yices.h' leaves __YICES_DLLSPEC__ unchanged if it's already defined

All code that includes 'yices.h' in the source tree must make sure
to define __YICES_DLLSPEC__ to '__declspec(dllexport)' before
the line #include "yices.h"

Also, to make it possible to link with 'libyices.a' on Windows, we
provide the flag NOYICES_DLL. If this flag is defined when 'yices.h'
is included then __YICES_DLLSPEC__ is empty.
