Makefiles: use our own makefiles rather than eXept's
...found in `stx/rules`. eXept's makefiles doesn't really
fit Smalltalk/X jv-branch needs - they're cluttered with
workarounds for long unsupported tools and platforms. In the
past we had to monkey-patch them here and there.
From this commit on, building requires GNU Make on UNUX-like
and GCC or Clang toolchain on both UNIX-like and Windows.
There we use MSYS2 environment.
This is a followup for 6fcb351d23a7.
# Makefile library for Smalltalk/X jv-branch
This directory contains makefiles for building individual
Smalltalk/X packages.
## Background & Rationale
Essentially this is a replacement for eXept's definitions in
`stx/configurations` and `stx/rules`. eXept's makefiles don't fit
Smalltalk/X jv-branch needs. In the past, we used to monkey-patch eXept's
makefiles and tweak them here and there, but this lead to a big mess (not a
surprise) in `rakelib/compile.rake`.
As we want to support more OS/CPU combinations, thing would go rather
wild and truly messy. Hence we provide our own, starting off with
eXept's definition. The plan is eventually to clean them up to the point
we understand how it works and then rewrite build process of individual
packages to unify *NIX and Windows builds (since Windows now use different
schema based on ancient, unmaintained Borland make).
Time will show if this ever become true. Let's hope.
