Compilation problem under Win XP

I'm trying to compile Ice 1.01 under Windows XP using the .NET Visual environment (and after having installed all the required components - DB, openssl, etc.)

I have had a first problem with IceUtil/UUID.cpp where the conditionnal test (and the similar test on line 47):
#if _MSC_VER > 1200
wchar_t* str;
#else
unsigned char* str;
#endif
generated errors. I had to remove the test to force an 'unsigned char' declaration and generate the executable.

The second issue is when I try to build the Ice directory. I get a message like :

---

Build started: Project: Ice, Configuration: Release Win32

../../include\Ice\Proxy.h(88) : error C3861: 'Context': identifier not found, even with argument-dependent lookup

And the same messages are repeated afterwards for other CPPs.

I don't understand the error message as the declaration seems perfectly right into the Proxy.h file. Is it an issue with the Windows compiler configuration ? A missing option ?

Thanks for your help.
