RFR: jdk8-tl builds windows builds failing in corba - javac: no source files

The JDK build broke because the JDK couldn't find the CORBA inbound files.

Needs to be quoted due to Windows separator being a semi-colon:

JAVAC:   is path separator
CYGWIN:  is statement/command separator

I also did two minor indention cleanups.  I know there are some inbound 
CORBA cleanups, is this ok?  Please see the patch file for the complete 
list, as "webrev -b" isn't working for whitespace changes.
