This patch adds a switch --with-libgcc to configure. When passed it prevents libtcc1.a from being built and links to /lib/libgcc_s.so.1 instead of PREFIX/lib/tcc/libtcc1.a. It will work on ARM when using libgcc from GCC >= 4.2.0. Prior versions don't have the __floatun[sd]i[sdx]f functions. It won't work on i386 because of two missing symbols emitted when floats are cast to integers, but users can provide those symbols (global short constants) in their code if needed. Daniel
