A macro processor that is used automatically by the GNU C compiler to transform programs before actual compilation.

AddressSanitizer (ASan) is a fast memory error detector. It finds use-after-free and {heap,stack,global}-buffer overflow bugs in C/C++ programs.

This is used to develop subsets of the libstdc++ shared libraries for use on custom installation floppies and in embedded systems.

One goal of sequencing based metagenomic analysis is the quantitative taxonomic assessment of microbial community compositions. However, the majority of approaches either quantify at low resolution (e.g. at phylum level) or have severe problems discerning highly similar species. Yet, accurate quantification on species level is desirable in applications such as metagenomic diagnostics or community comparison. GASiC is a method to correct read alignment results for the ambiguities imposed by similarities of genomes. It has superior performance over existing methods.

The Free Pascal Compiler is an Object Pascal compiler supporting both Delphi and Turbo Pascal 7.0 dialects, as well as Mac Pascal dialects. It provides a completely portable RunTime Library (RTL) available on many platforms and compatible with Turbo Pascal, along with a platform-independent class-based Free Component Library (FCL) adding many Delphi extensions and interfacing with many popular open source libraries.
