Thank you for the reply!
The one click installer is moving to mingw on 1.9.  Since there are no
1.9 binaries available, I use the mingw devkit to install it.
When I do so [even though JAVA_HOME is well set, viz]

C:\dev\blade_copy\digitalarchive_trunk>dir "%JAVA_HOME%\include\jni.h"
05/22/2009  02:35 PM            67,831 jni.h

mkmf.log has this to say...

"failed"
"gcc -E -I. -Ic:/ruby18/lib/ruby/1.8/i386-mingw32 -I. -IC:\Program
Files\Java\jdk1.6.0_13\include -IC:\Program
Files\Java\jdk1.6.0_13\include\win32   -g -O2  -IC:\Program
Files\Java\jdk1.6.0_13\include -IC:\Program
Files\Java\jdk1.6.0_13\include\win32  conftest.c -o conftest.i"

which doesn't compile because the paths need to be surrounded by quotes, like

gcc -E -I. -Ic:/ruby18/lib/ruby/1.8/i386-mingw32 -I. -I"C:\Program
Files\Java\jdk1.6.0_13\include" -I"C:\Program
Files\Java\jdk1.6.0_13\include\win32"   -g -O2  -I"C:\Program
Files\Java\jdk1.6.0_13\include" -I"C:\Program
Files\Java\jdk1.6.0_13\include\win32"  conftest.c -o conftest.i

so in order for a poor bloke like me to use rjb, it'll either need to
be distributed with "fat binaries" such that it has a precompiled
binary for mingw on 1.9, or the extconf would need to be changed
slightly to make it mingw compatible.

Sorry for the confusion.
