Windows, unfortunately, is not an option (I'd happily avoid tyo use
it). 
msys2 / mingw-64 could be an option: I've more experience with cygwin,
so I've chosen this solution. Another reaso for choosing cygin is that
I could use an older version which made it possible to build old 1.5.2
crosstool: I don't know if there's an equivalent "time macine" for
msys2 / mingw-64.

My hope, now, is that there's a known fix for the error I stumbled into

thank you
