--enable-shared in gcc 2.95 and earlier affects the C++ runtime only
(and Java runtime, if built).  libgcc is always static.

GCC 3.0 will switch to a shared libgcc, IIRC.  It's not perfect but
rather trades one set of problems for another.  EH is one of the main
considerations.

I don't know how much, if any, of this is applicable to Win32 however. 
Having --enable-shared do the right thing for mingw may require patches,
and it's not clear who is maintaining gcc for mingw these days.
