Thank you for your report. Can you show the error text?

Does it help to use 1024.0L here instead of just 1024.0?

Wouldn't it be better to cast to (double) ?

Wouldn't that be doing the same mistake? The compiler probably has a
point: an unsigned 64-bit number has more bits than a simple double
can handle.

Yes, it's a good reason for not doing the conversion automatically, but
IIUC we need a double, so we don't have much of a choice, and that's
what the cast to (double) would tell the compiler.

Sorry for omitting that. The error was:
w32.c(3820) : error C2520: conversion from unsigned __int64 to double not implemented, use signed __int64

Nope. Same error.
Else-thread, Stefan Monnier asked:
> Wouldn't it be better to cast to (double) ?
That doesn't help either. Each of these variations causes the same error:
totphys = (double)(memstex.ullTotalPhys / 1024.0);
totphys = memstex.ullTotalPhys / (double)1024.0;
totphys = (double)memstex.ullTotalPhys / 1024.0L;
totphys = (double)memstex.ullTotalPhys / (double)1024.0;

"Not implemented"? I'm not sure we want to support such a deficient
compiler. How about this:
DWORD tot_hi = memstex.ullTotalPhys >> 32;
DWORD tot_md = (memstex.ullTotalPhys & 0x00000000ffffffffLL) >> 10;
DWORD tot_lo = memstex.ullTotalPhys % 1024LL;
totphys = tot_hi * 4194304.0 + tot_md + tot_lo / 1024.0;
Does this work?

Indeed we don't.

Please don't install such hideous code just to work around a deficiency
in an obsolete proprietary compiler. Especially since there's
a perfectly good Free alternative available.

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

Yes.

The MinGW port of GCC.

Does it mean that the LL suffix is not supported in VS 6? Can you try
the same without the 2 LL suffixes?

I think so.

Yes, omitting the LL suffixes compiles with VS 6, though with several of
these warnings:
warning C4244: '=' : conversion from 'long double ' to 'long ', possible
loss of data
