I assume you meant "CLASSPATH" and "PATH".

Nope, symlinks will not help you (or at least, they probably won't).
If the program that looks at a particular environment variable is a 
Cygwin program, then the var should give a POSIX path. Otherwise it 
should give a Windows path. You should only have problems switching 
between the two if you have programs of both flavors looking at the same 
variable (other than PATH which Cygwin handles automagically).

Example: I assume you are using a non-Cygwin Java (I don't believe I 
have even heard of a Cygwin JVM, so that seems likely), therefore your 
JAVAHOME should be a Windows path, regardless of what shell (A cygwin 
*sh vs. Windows cmd) you are using.

Also see 'man cygpath'.
