At work we are running an OpenVMS/VAX (not Alpha) emulation on Windows boxes in order to run a cross-platform Ada-83 compiler (no longer in production, to my knowledge) to build the boot software for some aircraft flight systems. Do not expect that to be upgraded anytime soon -- bad enough it takes months for a sub-contractor to independently certify the boot software doesn't contain superfluous code, or unpredictable timings... Having to get a new build chain (OS, compiler, etc.) certified is not in the $$$. Heck -- we've had a study running just to certify a different toolchain where the only difference is WinXP vs Win7 -- when the toolchain doesn't even produce binaries for Intel architectures! IE: are the resultant binaries completely identical when the same source is built on each OS -- if there is ANY difference, it must be evaluated to be proven to have no effect. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
