Libtool developers --

FYI.  I don't know offhand if you're checking the intel compiler #defines for version numbers, but the following issue just came up on the Open MPI list: the intel 12.1.x compilers seem to have done terrible things to the version #defines.  So we're passing along this info in case you need it.

See below.

If the documentation is wrong, they should fix it; if the documentation is right, they should fix the compiler.  (However, there will still be an errant V12.1.0 that reports itself as 9999, so use of the version no. macros will never be reliable without a hack to handle this errant case.)  I'll report here what I find about the values of the version no. macros.  It is probably better, though, that automake/libtool rely on the output of icc -v, since that seems to always result in a value that matches the version of the product (as opposed to #define __INTEL_COMPILER 9999 and #define __ICC 9999 from within the V12.1.0 compiler).
