> What is the value of srcdir in top-level Makefile?

it is
  /home/dani/emacs/emacs.git

and FWIW, msys_to_w32 is
  sed -e 's,\\,/,g' -e 's,^/\([A-Za-z]\)/,\1:/,'

and strangely the printed value of w32srcdir is an empty string.  It
strange because:
* The output of the command employed to produce its value (echo
"${srcdir}" | ${msys_to_w32}) is "/home/dani/emacs/emacs.git".
* The occurrences of "@SRC@" in epaths.nt are actually replaced by
that string ("/home/dani/emacs/emacs.git") when written to epaths.h.
I'm attaching the diff between these two files.

BTW, I don't understand why there are two "$" in
"/^.*#/s|@SRC@|$${w32srcdir}|g", unlike the two previous lines (which
should be similar, I think).

Doing "source ./.gdbinit" didn't solve the problem, but I saw that the
contents of that file ("src/.gdbinit" from the build directory) are
this single line:
  source /home/dani/emacs/emacs.git/src/.gdbinit

so it occurred to me that perhaps giving that command to gdb could do
the trick.  And yes, it did.  So here we go:

$3 = (struct Lisp_String *) 0x36d0710 <__register_frame_info+57476880>
"c:/msys/home/dani/emacs/build/src/%emacs_dir%/share/emacs/24.3.50/etc/gnu"

No, the problem is already there: that path is wrong, obviously.
