> To test c89 compatibility, i wanted to compile lua 5.4.4 on a very old version  of MSVC. The compiler complains about the line 270 of lmathlib.c "#if (ULONG_MAX>>31>>31)>=3" with "Fatal error C1012:

In limits.h ULONG_MAX is defined like this:

#if __sizeof_long == 8
  #define ULONG_MAX 0xffffffffffffffffUL
  #define ULONG_MAX 0xffffffffUL

The first case looks weird to me ... I think this should write
#define ULONG_MAX 0xffffffffffffffffULL (ULL instead of UL).
