I just tried to build both icedtea6 and icedtea7 with this, but both
fail with the same error, similar to this one:

Earlier there is a warning about a version mismatch:

~~~~~~~~~~~~~~
WARNING: The file jvmti.h is not the same interface as the VM version.
          this workspace has jvmti.h 1.1.102 and 
          HOTSPOT_IMPORT_PATH contains jvmti.h 1.2.1 
 
WARNING: Possible HotSpot VM interface conflict. 
         HOTSPOT_IMPORT_PATH is used to import files from the VM build. 
         It is also used to verify that any copied files are consistent between 
         these two components. It has been detected that one or more of the 
         VM interface files inside this workspace may not match the interfaces 
         exported by the VM, or the VM versions could not be found. 
         The list of VM interface files is: 
             jvmti.h jvmticmlr.h. 
         This workspace has copies of these files at: 
           ./../src/share/javavm/export and ./../src/solaris/javavm/export 
         for build purposes, and they should contain the same interfaces 
         as the VM versions imported from: 
           $(HOTSPOT_IMPORT_PATH)/include 
                (i.e. /tmp/nix-build-icedtea6-1.13.7.drv-0/icedtea6-1.13.7/openjdk.build-ecj/hotspot/import/include) 
         If an interface indeed doesn't match, then the use of this interface 
         at JDK runtime could cause serious errors.

This is probably related.  Too bad.  I’ll try to figure out what’s going
on here.
