mingw target pathname error

[Vibhu M. <vi...@ho...>]

In September 2022, Bruno had mentioned some known file/filesystem trouble 
if building from Cygwin 64-bit targetting Cygwin 32-bit. I don't know if 
that's related to some observations I've made, so I'll report my 
observations anyway because they might be totally unrelated.

The problem occurs on both:
1) 64-bit Windows, 32-bit Cygwin, targetting 32-bit Mingw
2) 32-bit Windows, 32-bit Cygwin, targetting 32-bit Mingw
and does not occur in any of the following places I've tested targetting 
Cygwin:
3) 64-bit Windows, 64-bit Cygwin, targetting 64-bit Cygwin
4) 64-bit Windows, 32-bit Cygwin, targetting 32-bit Cygwin

This is the problem.

Z:\clisp_20240322\builds\tryc32m32>lisp -M lispinit.mem -norc -ansi -q
[1]> (directory (make-pathname :type :wild :name :wild))

*** - Internal error: statement in file "../src/pathname.d", line 3769 has 
been reached!!
       Please see <http://clisp.org/impnotes/faq.html#faq-bugs> for bug 
reporting instructions.
The following restarts are available:
ABORT          :R1      Abort main loop
Break 1 [2]> :a
[3]>

Without the -norc, the error occurs even before the first clisp prompt, 
presumably from trying to look up the rc file.
