As I understand it, libc.so is roughly analogous to the core DLLs:
kernel32, etc. Look in gcc/config/i386/mingw32.h and cygwin.h for
some lists.
The interfaces defined by the C standard will be provided by some
library - that's what Bo means. Some of the interfaces defined by
POSIX are present too, more with cygwin. Very unix-specific routines
like getpwent naturally won't show up.
It's a historical accident that libc.so contains all the stuff it
does. In fact, you can make a good design case for splitting it up by
standard and interface level. (Some systems have a libsys.a that
contains nothing but the primitive system calls, for use by programs
that don't want the C runtime. Unfortunately it doesn't work with
dynamic linking.)
