[openssl-users] MinGW64 / MSYS2 and ./Configure : use of Windows style path causing failures to 'make'

[Ron Gaw <ronmlgaw at yahoo dot com>]

I am using a MinGW64 / MSYS2 environment to compile OpenSSL1.1.0c, but failing consistently after multiple attempts with a few variations each attempt (including deleting entire source directory and re-untar/ungzipping).   I believe there's something wrong either with my environment settings or ./Configure options.  This is the output of ./Configure after setting only the CFLAGS env var:
$ export "CFLAGS=-03"$ ./Configure mingw64 --prefix=/usr/local zlib shared

Configured for mingw64.

$ make
C:\msys64\mingw64\bin\perl.exe "-I." -Mconfigdata "util\dofile.pl" \
    "-oMakefile" crypto\include\internal\bn_conf.h.in > crypto\include\internal\bn_conf.h
/bin/sh: C:msys64mingw64binperl.exe: command not found
make: *** [Makefile:701: crypto\include\internal\bn_conf.h] Error 127


It seems the "\" is the culprit here, since the execution of the make command appears to strip those out and then (as expected) the /bin/sh cannot recognize that large hash of what should have been the path to Perl.  I did edit the first Makefile above to :    Change the base PERL to "C:/msys64/mingw64/bin/perl.exe", *and*
    crypto/include/internal/bin_conf.h.in > crypto/include/internal/bin_conf.h
The above worked, but *only* for that line of the make file (as I expected).  It then fails at the very next line because I didn't edit every "\" to become "/" instead.  I'm not sure I'm willing to do that much editing... seems there's got to be a better way to make this work.

I realize this has something to do with specifying ./Configure mingw64 .... and how it's populating the Makefiles using Windows-style paths, but I'm not sure it's safe / okay to fake having a Unix build target instead, since this will likely create new / other problems with libraries, etc.
Am I missing a ./Configure option, an environment variable I should preset, or something else altogether?
