Also I searched for the definition 'FD_CLOEXEC' I didn't find this from any of the files.
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...
