 * Using section attributes, embed the specified version in the "modinfo"
 * section of the ELF binary. We don't do this on Windows, where the PE format
 * already has version information stuffed inside it, nor on Mac OS X, which
 * doesn't use ELF.
 *
 * We can't declare vm_version as static, otherwise it may get optimized out.
 * I've seen this when building with gcc 4.1, but not with 3.3.
 *
 * The argument to the macro should be the base name for the version number
 * macros to embed in the final binary, as described in vm_version.h (see
 * declaration of VM_VERSION_TO_STR).
