In-Reply-To: <pull.1068.v4.git.1635867971.gitgitgadget@gmail.com>

From: =?UTF-8?q?Carlo=20Marcelo=20Arenas=20Bel=C3=B3n?= <carenas@gmail.com>

d5cfd142ec (tests: teach the test-tool to generate NUL bytes and use it, 2019-02-14), add a way to generate zeroes in a portable way without using /dev/zero (needed by HP NonStop), but uses a long variable that is limited to 2^31 in Windows.

Use instead a (POSIX/C99) intmax_t that is at least 64bit wide in 64-bit Windows to use in a future test.
