Subject: Prevent msys2 conversion of "cmd /c" switch to a file path
X-Git-Tag: REL_13_BETA1~1516
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=73ff3a0abbbcb2c623731b88f2d1334bc67e5820;p=thirdparty%2Fpostgresql.git

Prevent msys2 conversion of "cmd /c" switch to a file path

Modern versions of msys2 have changed the treatment of "cmd /c" so that
the runtime will try to convert the switch to a native file path. This
patch adds a setting to inhibit that behaviour.

Backpatch to all live branches.
