cc/gcc programming - where are the includes?

[Christoph Kukulies]

I was refering to compiling a C program in a terminal shell using a makefile or command line.
Indeed it seems to work without CPATH set. I had a type in my #include <sys/types.h> line :-(
Had some strange character in that line from copy/paste.
Sorry for that. All fine now.

I need to run a small server on my mac as well and I thought the best would be to run it in a terminal and compile it with a C-compiler of choice. Need not to be gcc. Just the default one. And thanks Ruben for the tip using the CPATH variable.
