Good - that looks OK.

After installing bits from there, I needed to copy bin/freetype6.dll
to lib/freetype6.dll

And then edit the makefile to reach for freetype6.dll, as you
did.  Here are my diffs:

% pwd
/cygdrive/g/OpenJDK/jdk/make/tools/freetypecheck

$ diff -u  Makefile.00 Makefile

+  FREETYPE_DLL = $(FREETYPE_LIB_PATH)/freetype6.dll
   FT_LD_OPTIONS  = $(FREETYPE_LIB_PATH)/freetype.lib
 else
   FT_OPTIONS  = $(CFLAGS)

Unfortunately, the freetype_versioncheck.exe that is created after
doing that fails to initialize:

When run in a Cygwin window:
$ g:/OpenJDK/build/windows-i586/btbins/freetype_versioncheck.exe
$ echo $?
34

When run in a DOS cmd window, I get an "Application Error" pop-up
that reads "The application failed to initialize properly (0xc0000022).
Click on OK to terminate the application" [OK]

If I look at freetype_versioncheck.exe using the dependancywalker
tool [1], it shows an unresolved reference to ZLIB1.DLL


When I switch my OpenJDK build environment back to use my existing
copy of freetype 2.3.4 [2], the versioncheck program builds, works
OK (no mention of ZLIB1.DLL), and prints:

$ g:/OpenJDK/build/windows-i586/btbins/freetype_versioncheck.exe
Required version of freetype: 2.3.0
Detected freetype headers: 2.3.4
Detected freetype library: 2.3.4
$ echo $?
0

You could add "echo" lines to the commands run by a make rule.
Also, make commands are prefixed with '@' to make them silent.
Remove the '@' to see more output.
