Makefile system
---------------

Crawl uses a selector makefile (under source/makefile) to control what platform
it's building for. Your first step in building Crawl should be to edit
source/makefile and point it at the correct platform makefile. For instance, if
you're building for Windows, you'd use MAKEFILE=makefile.mgw to build with MinGW
for Windows (# is used for comments in makefiles).
Consult the operating-system specific sections for detailed information on
building Crawl. When you're done building Crawl, look at the section "Data
files" for important information on what files Crawl needs as it starts up.

by setting UNICODE_GLYPHS = y in makefile.unix.

by setting USE_UNICODE on the 'make' command line.

NOTE: You cannot build Windows binaries on Windows 9x/ME using the MinGW
makefile supplied (which needs the cmd.exe shell of the Windows NT family). If
you're on 9x/ME, you can use the Cygwin build instructions, or build a binary on
a Windows NT/2k/XP system (the binary will run on 9x), or build a DOS binary.

As of 0.4.2, PCRE 7.7 source is included with Crawl.  It is enabled by default.
The sources in pcre/util are identical to the 7.7 distro except for removed
cmake, doc, and testdata folders (unused by Crawl) and a hand-rolled Makefile.

As of 0.6.0, PCRE 7.9 source is included with Crawl.  It is enabled by default.
The sources in contrib/pcre are identical to the 7.9 distro except for the use 
of a custom-made Makefile instead of the automake system that was in place 
previously.
