PentiumGCC is a branch of GCC (the GNU Compiler Collection, formerly known as gcc/egcs) especially designed to optimize for x86 compatible chips. Speed improvements of 2-30% are possible. MMX support for P-II is being worked on. Since PentiumGCC is distributed as a patch to GCC, you will need to get the source code for the main GCC distribution to compile PentiumGCC.
jiffyc is a replacement for rmic, a program that generates the stub and skeleton files needed by distributed applications/applets based on Java RMI. But as it is written in C++, it is substantially faster than rmic. It can be used with either the 1.1 and the 1.2 protocol versions. Development has started to support even RMI over IIOP.
The Information System Development Kit gives the developer a platform-independent method of creating Information Systems with data forms, SQL database access, database-browsing support, report generator and many other useful features. ISDK is now in a development stage and it is available only for the Linux operating system. The form module now works on text terminals using the ncurses library (not functional right now), and on the X-Window system using the GTK+ toolkit.
GNAT (formerly the GNU NYU Ada Translator) is a full Ada compiler and runtime library supporting Ada 2005, Ada 95, and Ada 83. It is a full implementation of the language, including all of the optional Annexes of the Language Reference Manual. It is based on GCC technology, and has source, pre-packaged releases, and several additional Ada tools available. The runtime has a modified GPL so that your applications don't have to be GPLed automatically.
