The 'gcc' in your log is the Cygwin GCC ! So it uses its own "Cygwin
target headers" when compiling something for Cygwin :

>>> gcc -c -DHAVE_CONFIG_H -g -O2 -I.
 >>> -I../../Gcc_Source/gcc-4.3.3/libiberty/../include

But other headers could be required additionally...

So the 'fcntl.h' should be in your Cygwin target headers in
'/usr/include' or something !

A sanity check :

Can your GCC compile and link anything?  For instance the
famous "Hello World" ?  If you cannot do this, how you
could imagine your compiler to succeed in compiling GCC
from its sources ?

Probably it is possible to download and install only the
GCC part but no headers and no libraries for Cygwin...
