+Subject: [PATCH] lib/util-get-random-bytes.c: fixed conversion error with
+ mingw
+
+With x86_64-w64-mingw32-gcc. get below error:
+| ../git/lib/util-get-random-bytes.c: In function '_crypt_get_random_bytes':
+| ../git/lib/util-get-random-bytes.c:140:42: error: conversion from 'size_t'
{aka 'long long unsigned int'} to 'unsigned int' may change value
[-Werror=conversion]
+| 140 | ssize_t nread = read (fd, buf, buflen);
+| | ^~
+
+In util-get-random-bytes.c, has get_random_bytes(void *buf, size_t buflen),
+but in mingw-w64-mingw-w64/mingw-w64-headers/crt/io.h, read() has "unsigned
int"
+read(int _FileHandle,void *_DstBuf,unsigned int _MaxCharCount), and has:
+ #ifdef _WIN64
+ __MINGW_EXTENSION typedef unsigned __int64 size_t;
+ #else
+ typedef unsigned int size_t;
+ #endif /* _WIN64 */
