* win/tclAppInit.c: Restored the 'setargv' procedure when

compiling with mingw.  Apparently, the command line parsing in
mingw doesn't work as well as that in vc++, and the result was
(1) that winPipe-8.19 failed, and (2) that 'make test' would
work at all only with TESTFLAGS='-singleproc 1'. [Bug 967195]
