Tokyo Cabinet and cygwin

Question

I am trying to install Tokyo Cabinet under Windows Cygwin but when I run ./configure I get the following error:

configure: error: regex.h is required

Answer 1

From a stock Cygwin installation, this can be fixed by installing the gcc4-core package. Make sure to check Select required packages (RECOMMENDED).

However if you are trying to cross compile you will need to install PCRE.
