42: $! First we figure out what needs to be done. This is sort of like a limited
43: $! make facility - the command line options specify exactly what components
44: $! we want to build. The following options are understood:
45: $!
46: $! LINK: Assume that the object modules for the selected compiler(s)
47: $! have already been compiled, perform link phase only.
48: $!
49: $! CC1: Compile and link "C" compiler.
50: $!
51: $! CC1PLUS:Compile and link "C++" compiler.
52: $!
53: $! CC1OBJ: Compile and link objective C compiler.
54: $!
55: $! ALL: Compile and link all of the CC1 passes.
56: $!
57: $! INDEPENDENT:
58: $! Compile language independent source modules. (On by default).
59: $!
60: $! DEBUG: Link images with /debug.
61: $!
62: $! If you want to list more than one option, you should use a spaces to
63: $! separate them.
64: $!
65: $! Any one of the above options can be prefaced with a "NO". For example,
66: $! if you had already built GCC, and you wanted to build G++, you could use the
67: $! "CC1PLUS NOINDEPENDENT" options, which would only compile the C++ language
68: $! specific source files, and then link the C++ compiler.
69: $!
70: $! If you do not specify which compiler you want to build, it is assumed that
71: $! you want to build GNU-C ("CC1").
