-# The MSYS2 run-time convert arguments that look like paths when executing

-# exact conversion rules are listed here:
-#
-#       http://www.mingw.org/wiki/Posix_path_conversion
-#
-# With the built-in configurations (all having names starting with "mingw"),
-# the openssl application is not linked with the MSYS2 run-time, and therefore,
-# it will receive possibly converted arguments from the process that executes
-# it.  This conversion is fine for normal path arguments, but when those
-# arguments are URIs, they sometimes aren't converted right (typically for
-# URIs without an authority component, 'cause the conversion mechanism doesn't
-# recognise them as URIs) or aren't converted at all (which gives perfectly
-# normal absolute paths from the MSYS viewpoint, but don't work for the
-# Windows run-time we're linked with).
-#
-# It's also possible to avoid conversion by defining MSYS2_ARG_CONV_EXCL with
-# some suitable pattern ("*" to avoid conversions entirely), but that will
-# again give us unconverted paths that don't work with the Windows run-time
-# we're linked with.
-#
-# Checking for both msys perl operating environment and that the target name
-# starts with "mingw", we're doing what we can to assure that other configs
-# that might link openssl.exe with the MSYS run-time are not disturbed.
