I'm helping (!?) my wife learn C, and she's stumbled over a missing
include file, #include <iostream>.

She's working from the terminal, and has Xcode 2 installed. It's gcc
4.0, and the include file is there:

homeboy% gcc --version
powerpc-apple-darwin8-gcc-4.0.0 (GCC) 4.0.0 20041026 (Apple Computer,
Inc. build 4061)

homeboy% find /usr/include -name iostream
/usr/include/gcc/darwin/3.3/c++/iostream
/usr/include/gcc/darwin/4.0/c++/iostream

The error msg is
homeboy% gcc peapods.c
peapods.c:1:20: error: iostream: No such file or directory

If I'm so bold as to include the path to iostream the world blows up:

homeboy% gcc -I/usr/include/gcc/darwin/4.0/c++/ peapods.c
In file included from peapods.c:1:
/usr/include/gcc/darwin/4.0/c++/iostream:44:28: error:
bits/c++config.h: No such file or directory
In file included from /usr/include/gcc/darwin/4.0/c++/ios:44,

                from peapods.c:1:

/usr/include/gcc/darwin/4.0/c++/iosfwd:47:25: error: bits/c++io.h: No
such file or directory...
and 4000+ more lines of err msgs.

An Xcode Command Line C++ project compiles and runs fine with her code.

What's up here?

TIA.
