RE: allow specific flags through to the linker without modification

[Boehne, Robert]

Howard,

IIRC, -XCompiler will pass an argument directly to the compiler
when mode==compile, if you need to pass something to the compiler
during linking, you might need to use -XCClinker instead.
Example:
 I'd like to have "CC -z defs ..." on my link line (not that
this is the way to pass this particular flag):
libtool --mode=link --tag=CXX CC -XCClinker -z -XCClinker defs ...

The mechanism is rather simple, it just plops the argument on
the command line without changes.  This should be exactly what
you'd want though.

Ah, I missed that "-Xcompiler" option. If I use "-Xcompiler -Wc,DLL" will the 
compiler then get invoked as "cc -Wc,DLL" ? If so, this works for me.
