building moz m117

Building moz on 680_m117 with cygwin tcsh, I get this error

=============
Building project moz
=============
/cygdrive/c/downloads/openOffice/src680_m117/moz
dmake:  extractfiles.mk:  line 215:  Error -- Expecting
macro or rule defn, foun
d neither

The specific code in extractfiles.mk is this:

# copy files in RES_FILELIST
.IF "$(OS)"=="SOLARIS"
	@+$(COPY) $(MOZ_BIN_DIR)$/res$/charsetalias.properties
$(RUNTIME_DIR)$/res$/charsetalias.properties
.ELSE
	@echo No Res Files to copy.
.ENDIF

There are actually three instances of the test for
"SOLARIS", the first one being to create a /res directory.
It does not have an ".ELSE". The other two instances have
the .ELSE  which appears to crash the compiler.

How can that be? If that is the case, and the .ELSE
followed by "@echo"  acts like an assert(), then this code
should not build for anything other than Solaris. Since
google doesn't mention other people with this issue, it
seems more like something I might have missed in the
configure stage.

I did not disable mozilla. I did put the precompiled
binaries in /moz/zipped

I believe I followed all the other instructions found at
http://tools.openoffice.org/dev_docs/build_windows_tcsh.html

What am I missing?

Thanks
