Both are roughly 20-100 times as large as they should be.

glibc _is_ full of dubious features. Take the list of functions
defined in POSIX/SUSv3 and diff it against the list of symbols in
glibc. The differences are all GNU extensions which no portable
program (i.e. most all real-world programs) will use.

gcc is full of nonstandard extensions which people _do_ use, making
their programs extremely gcc-dependent. A few of these are useful;
most are "dubious features". Overall it's is bad because a replacement
for gcc could compile code 3-100 times faster (depending on
optimization levels) and generate better code, but it's hard to
duplicate both the full C language _and_ all the gcc-extension crap on
top of it. These days almost all of gcc development efforts go into
useless C++ stuff (and other unnecessary languages), and rather than
keeping this bloat separate they integrate it into the core and make C
programs suffer the consequences.

I could rant for 100kb on all the bloat and bugs of gcc and glibc but
I won't right now. If you really want to know more ask me in private
and I'll send you some docs.
