I would happily use a newer compiler. The file emacs/nt/INSTALL says
this:
To compile Emacs, you will need either Microsoft Visual C++ 2.0, or
later up to 7.0, and nmake
I didn't realize that I could use a version of VC++ newer than 6.0. I
would be happy to abandon 6.0 for building Emacs on Windows. Is VC++
7.0 the compiler that comes with Visual Studio 2003?
What compiler do the Emacs developers use to build on Windows?

Nope:
w32.c(3823) : error C2059: syntax error : 'bad suffix on number'
w32.c(3823) : error C2146: syntax error : missing ')' before identifier 'L'
w32.c(3823) : error C2059: syntax error : ')'
w32.c(3824) : error C2059: syntax error : 'bad suffix on number'
w32.c(3824) : error C2146: syntax error : missing ';' before identifier 'L'
w32.c(3824) : error C2065: 'L' : undeclared identifier
Here's the relevant code with line numbers:
3819 if (global_memory_status_ex (&memstex))
3820 #if 1
3821 {
3822 DWORD tot_hi = memstex.ullTotalPhys >> 32;
3823 DWORD tot_md = (memstex.ullTotalPhys & 0x00000000ffffffffLL) >> 10;
3824 DWORD tot_lo = memstex.ullTotalPhys % 1024LL;
3825 totphys = tot_hi * 4194304.0 + tot_md + tot_lo / 1024.0;
3826 }
3827 #else
3828 totphys = (signed __int64)memstex.ullTotalPhys / 1024.0;
3829 #endif
