Installed Singular/SW can be moved...
Fix building without Python
chg: StringAppend/StringSetS/StringEndS: use multiple times
Fixing 'make check' due to Hans's "chg: StringAppend/StringSetS/StringEndS: use multiple times"
Replace --no-{rtti,exceptions} by -fno-{rtti,exceptions}

This improves compatibility with clang. Moreover, to the best
of my knowledge, the --no-* variants are undocumented to start with.
At least the GCC manuals for all versions from 2.95.3 till 4.7.2
only list the -fno-* variants, as far as I could tell.
Silence some warnings about statements without effect

Fix main() prototype of libparse

Conflicts:
	Singular/libparse.l

The correct official spelling is indeed "Mac OS X". This is in

as in "MacOS 7".
