Microport Inc, Scotts Valley, California, which recently became the first non-hardware licensee of Unix System Laboratories Inc’s unannounced System V.4.2 ES/MP, has started shipping an ANSI C Compiler for Intel Corp’s Pentium processor from Unix System Laboratories Inc. The optimised compiler has a blended mode option for applications that will run on 80486 and Pentium boxes as well as a Pentium-only mode. Microport thinks it is the first Unix Labs licensee to make the compiler available in shrinkwrapped form. It is available as a $400 option on Microport’s multi- and uniprocessor Unix System V.4 software. The new compiler is said to be some 10% to 20% faster than the top-ranked GNU C Compiler.
