2.7.3 from R. Klaren builds nicely under VC6.0 (WIN2000) and I can
successfully Antlr the examples (like calc and tinyc).  I have also 
been able to build the CGRAM project using NMAKE on the include
makefile located in the Grammars directory of cgram using both 
2.7.1 and 2.7.2.

When I try to NMAKE the CGRAM files at the command line using 2.7.3 I
get the following error:

ANTLR Parser Generator  Version 2.7.3 (20031209-72)  1989-2003
Exception in thead "main" java.lang.UnsupportedClassVersionError:

   at java.lang.ClassLoader.defineClass0(Native Method)
   at java.lang.ClassLoader.defineClass(Unknown Source)
   at java.security.SecureClassLoader.defineClass(Unknown Source),

Any ideas?  Thanks
