Building cygwin

[smr xxxx]

I'm trying to diagnose a problem with fstat and lseek not working as
expected with stdin on Vista Enterprise SP1.

Anyway, I've grabbed the src package via setup.exe, and am trying to
build, with no luck so far.  I've tried the instructions in the
included README (./configure ; make ; make install) and also those in
the FAQ (http://cygwin.com/faq/faq-nochunks.html#faq.programming.building-cygwin).
 Using the FAQ instructions I get an error about non-existence of c++,
so I tried "CXX=g++ /oss/src/configure" instead, and it gets me
further but fails on trying to find awk (at least I think the compile
error below is due to not having found awk in the prior step).  I've
tried AWK=gawk but it didn't help.

Can anyone offer any instructions on how to build cygwin?  All I'm
interested in doing right now is adding some printf's to fstat to work
out what's going wrong.
