Hi Gabor,

do you actually have a netdb.h ? What does

$ find /usr/include/ -name netdb.h

print ?

You can check which directories gcc searches for include files by
adding the -v switch to the gcc command line:

gcc -v getip.c

netdb.h is part of the cygwin package (according to
http://cygwin.com/cgi-bin2/package-grep.cgi?grep=netdb.h) which is
always installed; it should be in /usr/include, which is searched by
gcc by default.
