Portability problems not fixed by Gnulib:

  * This function is missing on some platforms: mingw, BeOS.

  * Attempts to shmat into a previously malloc-ed region fail on SunOS 4, with errno set to EINVAL, even if there is an munmap call in between.

  * On Linux, the flag SHM_REMAP is needed in order to force shmat to replace existing memory mappings in the specify address range.  On other platforms, it is not needed.
