Sure. You patch it ? The LINUX_VERSION_CODE example you sent me
[ NB:
  #define UTS_RELEASE "2.2.19"
  #define LINUX_VERSION_CODE 131603
  #define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))

  used as

  #if LINUX_VERSION_CODE <= KERNEL_VERSION(2.2.19)
]

looks fine.

I want to add a version() command in gp [ and a preprocessor construct for
~/.gprc ] so as to be able to test the version number before using relatively
new features. I'm fed up with (older) gp exiting on startup because #L for
length(L) is undefined, or a useful new default does not exist.

It will not cure past versions, but if I had done it when I first thought
about it, it would have been fixed 5 years ago...

OK. Patch ?
