Please let's not do that on MS-Windows at least. Dynamically linking
against these two libraries has the following 2 adverse effects:
. it requires any site that distributes precompiled Windows binaries
of GDB to also distribute the full humongous tarball of GCC
sources (because libgcc runtime exception doesn't cover dynamic
linking against shared libraries); and
. it opens the gates of the "DLL hell", since there's any number of
libgcc and libstdc++ DLLs from different versions of GCC floating
around on any given Windows system with GNU software, and there's
no practical way to ensure binary compatibility between the one
found first on PATH and a particular version of GDB one wants to
run
