vbcc - Volker Barthelmann's C compiler
The great compilers on AmigaOS (and for AmigaOS) like SAS/C and gcc (ADE/geekgadgets) are getting some serious competition by the name of vbcc, which is an acronym for "Volker Barthelmann's C compiler".
What makes vbcc great?
It...
...is cross-platform / portable
...can cross-compile for different targets
...is very fast
...produces small binaries
...has a clear concept, working default configurations, and is easily installed
...is actively developed with modern standards in mind
...still supports AmigaOS1.3 and plain 68000
