Why does the Windows build look for Solaris source files ?

[Phil Race]

I created a stripped down platform-specific set of sources for the 
Windows build
and although it doesn't look like it was fatal I see the following :-
## Starting jdk
/usr/bin/find: `/cygdrive/c/jdks/jdk8_2d/jdk/src/solaris/classes': No 
such file or directory
/usr/bin/find: `/cygdrive/c/jdks/jdk8_2d/jdk/src/solaris/classes': No 
such file or directory
/usr/bin/find: `/cygdrive/c/jdks/jdk8_2d/jdk/src/solaris/classes': No 
such file or directory

Seems like these shouldn't be needed to do a Windows build.
