I do not have a time machine.  The actual install was made more than a

in my report.  The rest of historical information is gone.

It is in
      FOO/bin/gcc.exe
When bash --login is started with an empty path, this one is on
      /mingw/bin/gcc.exe
(due to my symlink of MSYS’s /mingw to the native directory FOO).

Irrelevant.  You may think that FOO is f:/oo — it would be least
confusing.  Otherwise, if you want to confuse yourself MUCH more, FOO
is
        k:/get/emacs-build/mingw-get

This IS absolutely irrelevant.  Moreover, it was in many different
directories on different tries.  All that is important is that it was
on PATH when
    bash --login
was started.

When started with empty PATH, the first one is, as reported,
  .:/usr/local/bin:/mingw/bin:/bin:/usr/gnu/bin:/usr/local/bin:/bin:/usr/bin:.
The second one was, obviously, empty.

I won’t supply my default PATH for obvious reasons — and since it has
no bearing on half of the cases reported (empty PATH), and is
practically guaranteed to be irrelevant for the other half.

Inside FOO, the following directories have .h files:
    ./include/
    ./include/GL/
    ./include/ddk/
    ./include/gdiplus/
    ./include/libltdl/
    ./include/parts/
    ./include/sys/
    ./lib/gcc/mingw32/4.8.1/include-fixed/
    ./lib/gcc/mingw32/4.8.1/include/
    ./lib/gcc/mingw32/4.8.1/include/ssp/
    ./lib/gcc/mingw32/4.8.1/install-tools/
    ./lib/gcc/mingw32/4.8.1/install-tools/include/
    ./mingw32/include/
    ./mingw32/lib/gcc/mingw32/4.8.1/include-fixed/
    ./mingw32/lib/gcc/mingw32/4.8.1/include/
    ./mingw32/lib/gcc/mingw32/4.8.1/include/ssp/
    ./mingw32/lib/gcc/mingw32/4.8.1/install-tools/
    ./mingw32/lib/gcc/mingw32/4.8.1/install-tools/include/
    ./msys/1.0/include/
    ./msys/1.0/lib/perl5/5.8/Encode/
    ./msys/1.0/lib/perl5/5.8/msys/CORE/
    ./share/autoconf/
    ./share/gettext/
    ./share/gettext/intl/
    ./share/libtool/libltdl/
    ./share/libtool/libltdl/libltdl/

Likewise for .a files (removing excessive Perl “auto” subdirectories):

    ./lib/
    ./lib/gcc/mingw32/4.8.1/
    ./libexec/gcc/mingw32/4.8.1/
    ./mingw32/lib/
    ./mingw32/lib/gcc/mingw32/4.8.1/
    ./mingw32/libexec/gcc/mingw32/4.8.1/
    ./msys/1.0/lib/
    ./msys/1.0/lib/perl5/5.8/msys/CORE/
    ./msys/1.0/lib/perl5/5.8/msys/auto/B/
    ./msys/1.0/lib/perl5/vendor_perl/5.8/msys/auto/Alias/

N/A

As reported, the only one for which I needed to put a manual checkmark
was mingw32-base.  The rest of info is gone.

This info is gone (reliable one).  AFAICR, the only choice was the
install directory (FOO above).

===========================================

If I can squeeze it into a few minutes, I may try to redo installing
via mingw-get on a pristine computer (need to borrow it).
