This is the real problem with dual universes. Almost every vendor has
incorporated features from the both universes into their distribution.
Thus, users expect and demand these features wherever they go.

And where did they put getopt? Hidden away in a random library.

Here's how we solved the problem when I was at NBS.
First, I assumed I wanted a ucb system with att additions.
I went to /usr/include and did: 'ln -s /usr/att/usr/include/* .',
making available all the att include files that did not conflict with ucb.
I also did this in /usr/include/sys.

Then, I did a ln -s /usr/att/lib/libc.a /lib/libatt.a and linked
with cc -o prog a.o b.o ... z.o -lc -latt.

Notice that I used the real c library first!
