GSH is an implementation of a POSIX shell developed for the Windows platform. The aim of the project is to speed up builds of GNU projects on Windows in a large automated build infrastructures. GSH can be used to compile projects depending on autotools, UNIX make, ... It is up to 2-3 times faster than Cygwin shells for GCC builds.

In this talk I will present:

• what makes GSH faster than other Windows shells for building GNU projects;
• how GSH was developed;
• how you can use it to speed up your builds;
• the limitations;
• what features of Ada we benefit from in this project.
