add 83fbd4f32f3d2b77b5967e4e6025c3b748a189ae to Pd-l2ork: fixed bendin incorrect value (was range of 0-16383, now is -8192 to 8191)

another kludge-- bring back the code in makefile.mingw to compile everything in extra, and remove the expr~ external files

add x_preset.c and x_magicglass.c back to makefile.mingw-- they were accidentally removed in the big Vanilla backport

very stupid kludge just to get the code to compile on Windows-- this needs to get fixed by a more complete backport of Pd Vanilla's s_path.c code
