Every once in a while, on a multi-cpu machine, with high -j values, frysk build
mysteriously dies with this synopsis:

<obnoxious gcj command, entwined in shellouts, checks and scripts>
../../frysk-sys/lib/dwfl/DwarfDieFactory.java:76: error: Type ‘DwTag’ not found
in the declaration of the local variable ‘tagEncodings’.
        DwTag[] tagEncodings = DwTag.values();
           ^
../../frysk-sys/lib/dwfl/DwarfDieFactory.java:82: error: Type ‘DwTag’ not found
in the declaration of the local variable ‘tag’.
            DwTag tag = tagEncodings[i];
               ^
2 errors
make[1]: *** [lib/dwfl/Dwfl.h] Error 1
make[1]: *** Waiting for unfinished jobs....
chmod a-w lib/dwfl/DwTag.tmp
mv -f lib/dwfl/DwTag.tmp lib/dwfl/DwTag.java
make[1]: Leaving directory
`/usr/src/redhat/BUILD/frysk-0.0.1.2007.09.24/build/frysk-sys'
make: *** [all-recursive] Error 1

The problem is that for building Dwfl.h, frysk build system first compiles
.class files, and then induces appropriate .h files from them by way of gcjh. 
This is expressed in .java.h implicit rule.  But to build .class files, compiler
needs DwTag.java and other files... and this dependency isn't stated in Makefile.
