Lacking Natural Simplicity

To get Chicken version 2.207 to compile with MinGW I had to change the line in configure that read

mingw_libdir=`mingw32-gcc -print-prog-name=ld | sed 's%/lib/gcc-lib/.*%/lib%'`

with

mingw_libdir=`mingw32-gcc -print-prog-name=ld | sed 's%/lib/gcc/.*%/lib%'`

and copy posixwin.c over posix.c and uposixwin.c over uposix.c.
