Well Unix patch and unix diff - same job - different commandline options. You get them for VMS as well via GNV (GNU's Not VMS). >> There are 700kb worth of special changes to the standart GCC in order to >> make GNAT work pleasantly on OpenVMS.

I don't know! You have to ask AdaCore about that. Only they know if there is any release in the FSF repository which is also an officially released GNAT - or at least works well with VMS. But this is a problem for any OS. If you download the GNAT/GPL sources: There is a 700kb patch file for all OSes. Now the README.BUILD of GNAT/GPL says: | as well as a set of patches that you may need to apply to the | GCC sources, depending on your target platform. One of these patches is | "gcc-34.dif" and should be applied whatever the target. Only there are no target specific patch files in GNAT/GPL. There is a district 2 class society here and it is more the just the difference between GPL and GMGPL. The way it works: AdaCore commits there sources to HEAD of the FSF tree - but they don't actually use HEAD for GNAT/Pro and GNAT/GPL. Instead they backport the changes to some older - and presumably more stable GCC. And obviously they have to sets of patch files: general and target specific.
