You keep C++ programs in the root directory?!
Aside from that, however, this line reveals one (or maybe two) mistakes you
made:  You forgot to have gcc link in the iostream stuff (which you can do
by specifying -lgpp or -liostream); this would account for many of your
undefined symbols.  You also probably need to give GCC the -O or -O2 flag
so it can perform optimization (including inlining (!)).

that's because DOS uses a case-insensitive filesystem, so otherwise there
would be no way to tell string.h from String.h.  If all you need is the ANSI
C standard library string functions, however, just include string.h (which is
included by _string.h).
