Hi folks.  It's been 4 years with no progress here.

Is this becoming a WONTFIX or should we add a toplevel configure flag to give
the user an option to opt out of -static-libstdc++ -static-libgcc?

The the original patch has a work around, just specify --with-stage1-libs=" "
and you won't get the offending behavior :):

 # In stage 1, default to linking libstdc++ and libgcc statically with GCC
 # if supported.  But if the user explicitly specified the libraries to use,
 # trust that they are doing what they want.
 if test "$stage1_libs" = "" -a "$have_static_libs" = yes; then
   stage1_ldflags="-static-libstdc++ -static-libgcc"
 fi])

Should we make an explicit configury flag for this behavior instead of the
above work around?

Should we instead close this as a WONTFIX with a pointer to the following in
our docs:

--with-stage1-ldflags=flags
This option may be used to set linker flags to be used when linking stage 1 of
GCC. These are also used when linking GCC if configured with
--disable-bootstrap. If --with-stage1-libs is not set to a value, then the
default is ‘-static-libstdc++ -static-libgcc’, if supported.

Any input would be great.
