it doesnt build for me.. with tons of errors like

pes ~$ clang tw.parse.cpp 
In file included from ../../contrib/tcsh/tw.parse.c:1:
In file included from ../../contrib/tcsh/tw.parse.c:36:
In file included from ../../contrib/tcsh/sh.h:38:
/usr/include/stddef.h:57:19: error: cannot combine with previous 'type-name'
declaration specifier
typedef __wchar_t wchar_t;
                  ^

how did you get the preprocessed file? and/or how do you compile it?
