This line dereferenced the beginning of a string to read a single char,

This makes it possible to compile cfws with Visual Studio. Since winsock
and POSIX use very similar APIs, porting is mostly just a matter of
placing ifdefs around #includes and functions with slightly different
names.

However, CGI scripts and command line arguments are not available in
this port yet, since they used the Unix-exclusive getopt.h and popen.

This still doesn't throw up an error when attepting to run scripts
without the leading './', but it's a start

This can be used to view the values of environment variables passed to
CGI scripts.

Building each source file as a separate object makes it faster to
compile when only changing one source file, and also allows you to
compile with multiple threads when building the whole project.

This allows scripts to differentiate between the requested path and the
query parameters.
