Many newer programs will not even compile with libc5, i.e.
you need to use glibc2 or uclibc just to compile them. The
C programming language has changed somewhat since
libc5 was released.

About 1/8th to 1/4th the size of glibc, depending upon how it
is compiled. Roughly half the size of libc5.

Yes, uClibc is much better than libc5 for new programs.
There still some things that still only work right with glibc,
though. (e.g. MPlayer and the very latest version of netpbm,
I believe)

And that is why BL3 uses libc5. Because libc5 has many,
many more programs available for it than uClibc does.
