   make -f win/Makefile.mingw

If you have VC++ installed on your system, then consider:

   cd win; nmake /f Makefile.msc

If you have trouble, or you want to do something fancy, just look at
top level makefile. There are 6 configuration options that are all well
commented. Instead of editing the Makefile, consider copying the Makefile
to an alternative name such as "GNUMakefile", "BSDMakefile", or "makefile"
and editing the copy.

BUILDING OUTSIDE THE SOURCE TREE

An out of source build is pretty easy:

  1. Make and change to a new directory to do the builds in.

* Most *.c source files are preprocessed using a program called
  "translate".  The sources to translate are found in src/translate.c.
  A header comment in src/translate.c explains in detail what it does.

* The src/mkindex.c program generates some C code that implements
  static lookup tables.  See the header comment in the source code
  for details on what it does.
