I checked out master db3a7df and built it with MINGW64 console of
MSYS2 on 64bit Windows 10 version 1909. Then I got following error.
----------------------------------------------------------------------
CC search.o
CC regex-emacs.o
CC undo.o
CC alloc.o
CC pdumper.o
pdumper.c: In function 'dump_read_all':
pdumper.c:5078:60: error: conversion from 'size_t' {aka 'long long unsigned
int'} to 'unsigned int' may change value [-Werror=conversion]
5078 | ssize_t chunk = read (fd, (char *) buf + bytes_read,
chunk_to_read);

According to the result of git bisect, following commit is the cause
of the problem.
----------------------------------------------------------------------
commit 9e4e4775364490d31406f247237934dd7f203808 (HEAD)
Author: Paul Eggert <eggert@cs.ucla.edu>

In pdumper, simplify INT_MAX computation
* src/pdumper.c (dump_read_all): Avoid unnecessary cast.
Also, round down to page size, as sysdep.c does.
Also, don t assume INT_MAX <= UINT_MAX (!).
----------------------------------------------------------------------
If I go back to master db3a7df and revert this commit, then build
completes successfully.

I'm therefore closing this bug report.
