generate_bytecode_insn - tree code not implemented: min_expr

[Erik Poupaert]

In an attempt to compile org-xbill-DNS-1.4.1 natively, I bumped into a strange error
message:

err>org-xbill-DNS-1-4-1/src/org/xbill/DNS/Name.java: In class `org.xbill.DNS.Name':
err>org-xbill-DNS-1-4-1/src/org/xbill/DNS/Name.java: In method
`org.xbill.DNS.Name.compareTo(java.lang.Object)':
err>org-xbill-DNS-1-4-1/src/org/xbill/DNS/Name.java:806: error: internal error in
generate_bytecode_insn - tree code not implemented: min_expr

Does anybody know what it is?
