Actually after my patch commited in r4928 MinGW configure seems to
generate broken Makefile due MSYS bash bug. (Attaching cure/patch below)
The problem is that:
TEST=echo 'one\\ two\\ three\\'
echo “$TEST”
Should echo:
one
two
three\
Does it on Linux, Mac… all UNIX but not on MSYS (MinGW) which outputs:
one\two\three
(new lines removed, probably it doesn’t like backslashes)
Probably this bug should be submitted to MSYS team, but not waiting
till MSYS gets it fixed (they have very slow release cycles) here goes
simple cure…
My patch simply replaces single quoted SED rules where we needed
newlien injection with double quoted ones.
Tested on Mac, Linux & MinGW. Please review it ASAP coz this may be
showstopper for everybody compiling with MinGW.
Very sorry for not testing it properly on MinGW before the previous
patch went into SVN repo, but I expected MSYS bash will behave like
any other bash, but it doesn’t

Bump, can we have this patch reviewed and maybe committed, as
currently MinGW builds are broken without it :((

This is in, I’ve just been dragging my heels because all the
backslashes hurt my eyes.

Thanks.
Yeah, this is pretty obscure. I thought about just replacing
backquotes with $(…), which seems to do the job as well and not
suffer eating linebreaks on MSYS, but I think this exists only in
Bash, so it could break other Bourne shell compatible shells. Ended up
with those nasty doublequotes then 
If only there was a solution to somehow shorten “configure” time on
MinGW too. This makes me tear my hair out every time I need to check
the whole build process is working with MinGW :>–
