comparing the build logs on alpha and i386, this is the 
stamps/rt-class-files.stamp target, which succeeds to build on i386, but not on 
alpha. This target always uses the openjdk sourcepath, not the openjdk-ecj 
source path.

and it looks like the patch is applied, but ecj can't parse this value on alpha; 
the test program

  class Test {
        public static final float   MIN_NORMAL      = 1.17549435E-38f;
  }

fails to build:

----------
1. ERROR in Test.java (at line 2)
        public static final float   MIN_NORMAL      = 1.17549435E-38f;
                                                      ^^^^^^^^^^^^^^^
The literal 1.17549435E-38f of type float is out of range
----------


further, is it correct that the -ecj patch is applied to *both* the openjdk and 
openjdk-ecj directory?

$ ls -l build/openjdk*/jdk/src/share/classes/sun/misc/FloatConsts.java
-rw-rw-r-- 2 doko doko 4147 Feb 17 03:14 
build/openjdk-ecj/jdk/src/share/classes/sun/misc/FloatConsts.java
-rw-rw-r-- 2 doko doko 4147 Feb 17 03:14 
build/openjdk/jdk/src/share/classes/sun/misc/FloatConsts.java

these are still hard links.
