>Description:
Compiling a recent Classpath from CVS gives:

/usr/local/gcc-3.1/bin/gcj -C -d . @classes
./../java/security/Identity.java:207: tree check: expected class 't', have 'e' (expr_with_file_location) in unresolved_type_p, at java/parse.y:5028

This problem goes away when you remove the strictfp class modifier from java/lang/StrictMath.java.

(Note that you will soon hit bug #4715 - Tree check failure in check_inner_circular_reference, without the patch in that bug report.)
>How-To-Repeat:
Get either the latest CVS version of GNU Classpath or the latest release (0.0.3). (The latest release does not contain StrictMath yet but adding the strictfp class modifier to java/lang/Math.java gives the same results.)

./configure --with-gjc
make
>Fix:
The following horrible kludge seems to work around it.
