[Ecls-list] Some MinGW patches etc.

[Samium Gromoff]

Juan,

I have some patches in my ECL git tree, among which are:

  - some MinGW fixes,
  - a revert of a float-related crasher,
  - a src/Makefile.in improvement.

With these patches, I was able to build ECL with latest mingw-get-inst
(version 20100910).

Apropos the revert (which is an obviously improper fix, but a proper one
is way out of my competence area) -- the commit
655809781a6c2df3fc8b040d8be01f05177e31ec was making ecl_min bust the
stack during the build, like this:

And yet, one issue remains:

Still, loading them manually works just fine:

A couple strategically-placed FORMAT statements in src/lsp/module.lsp
revealed that the system's *MODULE-PROVIDER-FUNCTIONS* member serving 
REQUIRE suffers from NAMESTRING's misrendering of logical pathnames:

(namestring #P"SYS:ASDF") => "SYS:ASDF"
