          Issue ID: 24173
           Summary: ImportC: unable to parse microsoft extended integer
                    literals
           Product: D
           Version: D2
          Hardware: All
                OS: Windows
            Status: NEW
          Keywords: ImportC
          Severity: normal
          Priority: P1

Apparently MSVC has syntax for 32bit and 64bit integer literal suffix.

It’s like:

unsigned __int32 s = 0xffffffffui32;
unsigned __int64 s2 = 0xffffffffffffffffui64;
__int32 s3 = 0xffffffffi32;
__int64 s4 = 0xffffffffffffffffi64;
__int64 s5 = 12i64;
__int32 s6 = 07i32;

Encountered this as my copy of <stdint.h> defines SIZE_MAX using these
suffixes.

I can’t find where these suffixes are documented.
