Hi, Dmitry, in the future, post those issues directly to Firebird-devel,
please. I'm including the list in the discussion. More comments below:

This is what I found in my
F:\Languages\Microsoft Visual Studio\VC98\Include\winnt.h header file that
comes with MSVC 6:

typedef __int64 LONGLONG;
typedef unsigned __int64 ULONGLONG;

So basically you are changing the definition from unsigned to signed. Can
you try something like
#if !defined(_ULONGLONG)
typedef unsigned LONGLONG ULONGLONG;
#endif
and see if it's accepted? I don't know if MSVC5 has __int64 defined
internally, because I found that as a last resort, when the other
alternatives fail, winnt.h tries to define this:
typedef double LONGLONG;
typedef double ULONGLONG;
and in this case, the typedef shown above would fail.

It may be the case, but I don't know what they did in such case if it's not
in the source code.
