Subject: test-genzeros: allow more than 2G zeros in Windows
X-Git-Tag: v2.35.0-rc0~127^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=cbc985a1f403a09dd22511aca3e6699d3f3c1c7c;p=thirdparty%2Fgit.git

test-genzeros: allow more than 2G zeros in Windows

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.
