 Assuming Windows XP 32.  We will use MinGW to build the libraries and application and MSYS as a working environment.
-The distinction between MinGW and MSYS is very important: MinGW is a set of compilers and libraries you use to build Windows applications, while MSYS is a GNU environment similar to (and, in fact, based on) Cygwin.  You can //not// use MSYS libraries in your Windows application.
+The distinction between MinGW and MSYS is very important: MinGW is a set of compilers and libraries you use to build Windows applications, while MSYS is an emulated GNU environment similar to (and, in fact, based on) Cygwin.  You can //not// use MSYS libraries in your Windows application.  This means that you will sometimes have two copies of a particular library: an MSYS version used by MSYS tools, and a native version built with MinGW and used by MinGW tools and / or your application.
+===== Directories =====
+We will install MinGW into ''C:\MinGW'' and MSYS into ''C:\MSYS''.
+MSYS maps Unix-like paths to Windows paths: ''/'' translates to ''C:\MSYS'' and ''/mingw'' translates to ''C:\MinGW''.  In addition, all Windows drives will show up as ''/x'', where ''x'' corresponds to the drive letter, so ''/c/windows'' translates to ''C:\windows'', etc.
+We will install our libraries and applications into ''C:\met.no''.  You should start by creating that directory and the required subdirectories:
+  C:\> mkdir met.no
+  C:\> mkdir met.no\bin
+  C:\> mkdir met.no\include
+  C:\> mkdir met.no\lib
+  C:\> mkdir met.no\share
+  C:\> mkdir met.no\copyright

 At this point, you may want to download bsdtar from http://sourceforge.net/projects/mingw/files/MinGW%20Utilities/basic%20bsdtar/bsdtar-2.7.900a_r1628-20091110/ and install ''bsdtar.exe'' as ''/mingw/bin/tar''.  It supports a wider range of archive formats and compression algorithms than GNU tar, and automatically detects which one to use.
+You may want to install InfoZip's ''zip'' utility as well, since ''bsdtar'' can //extract// zip files but not //create// them: download the source code from http://sourceforge.net/projects/infozip/files/, extract it, and run the following commands in the source directory:
+  $ make -f win32/makefile.gcc
+  $ cp zip.exe /mingw/bin

-Or rather, in our brave GNU world, flex (http://downloads.sourceforge.net/project/mingw/MSYS%20flex/flex-2.5.35-1/flex-2.5.35-1-msys-1.0.11-bin.tar.lzma) and bison (http://downloads.sourceforge.net/project/mingw/MSYS%20bison/bison-2.4.1-1/bison-2.4.1-1-msys-1.0.11-bin.tar.lzma).  In addition, flex requires the GNU regex library (http://downloads.sourceforge.net/project/mingw/MSYS%20regex/regex-1.20090805-1/libregex-1.20090805-1-msys-1.0.11-dll-1.tar.lzma).  Download and install as usual.
+Or rather, in our brave GNU world, flex and bison.  There is a problem here: you can't use the MSYS versions, because they're not just build tools&mdash;bison includes a runtime library (''liby'').  Hence we need native versions of both tools.  We can get those from [[http://sourceforge.net/projects/gnuwin32|GnuWin32]].
+Download the following files from http://sourceforge.net/projects/gnuwin32/files/:
+  * the ''bin'', ''lib'' and ''dep'' zipfiles for the latest bison release (the ''dep'' zipfile contains a few libraries that bison needs, so you won't have to install them separately)
+  * the ''bin'' and ''lib'' zipfiles for the latest flex release
+For some unfathomable reason, both the flex and bison ''lib'' zipfiles contain incorrect copies of ''<unistd.h>''.  Either make a backup copy of ''/MinGW/include/unistd.h'' before you unpack them, or tell ''unzip'' (or ''bsdtar'') not to overwrite existing files:
+  $ tar -kxf bison-2.4.1-lib.zip -C /MinGW
+This will install a shell script called ''/MinGW/bin/yacc'' which incorrectly redirects to ''c:/progra~1/bison/bin/bison''.  Edit it so the entire script looks like this:
+  #! /bin/sh
+  exec /mingw/bin/bison -y "$@"
