libaddr2line.a is an invention from AdaCore several years ago; it is a
patch against the program "addr2line" in certain versions of binutils,
not GCC.  I am not aware of any binary distribution of it apart from
AdaCore's own.  In Debian, I've patched GCC so that it supports
symbolic tracebacks by calling addr2line in an external process rather
than using libaddr2line in-process.  An early version of this patch
was in the Ada for Linux Team distribution by Jürgen Pfeiffer for Red
Hat Linux 6 (in 1999).

So, I think you can have symbolic tracebacks in mingw in one of two
ways: patch binutils to build libaddr2line.a then link libgnat against
it; or patch libgnat to use the same method as on Debian.
