            Bug ID: 101779
           Summary: Compilation of rust-demangle.c fails on MinGW
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: demangler

This is because the data type 'uint' is not defined in the MinGW
headers.  I used uint32_t instead, and it compiled OK.
