Please note that this is *NOT* a vanilla 1.2.5.1 distribution of the
ROMIO package from Argonne National Labs.  Various customizations had
to be applied to the configuration process.  More to the point -- if
replace this copy of ROMIO with a newer version, it will likely not
work.  :-(

- The LAM Team

-----------------------------------------------------------------------------

Local modifications:
====================

- Modified configure[.in] to not add any -O* flags -- only use the
  ones passed in from the top-level configure script.
- Not all systems have snprintf(); replaced snprintf() in
  test/noncontig_coll2.c with strncpy()/null termination.
- Removed "MAKE=@MAKE@" from Makefile.in; allow the run--time
  specification to determine what it should be, not configure-time.
- Fixed weak symbols issue with gcc 3.2.x in fortran function names;
  must extern the function in conjunction with "#pragma weak" (fix
  suggested by ROMIO maintainers; will be in some future version of
  ROMIO).
- Removed man/man/MPI_Info_* MPI_Type_* so that they won't replace the
  corresponding LAM man pages.
- Essentially re-wrote util/romioinstall to do LAM-specific things
  (e.g., rename and move the resulting library).  Also allowed it to
  do uninstall.
- Hacked configure.in to add -DHAVE_STATUS_SET_BYTES to the LAM CFLAGS
- Changed adio/common/set_statsb.c to have a short subroutine to set
  status->st_length so that ROMIO knows how to set the number of bytes
  received in an MPI_Status object.  Thanks to Nina Thiessen for
  bringing this to our attention.
- Added bogusness to "use" unused arugments in the following files:
	mpi-io/delete.c
	mpi-io/rd_atalle.c
	mpi-io/read_alle.c
	mpi-io/wr_atalle.c
	mpi-io/write_alle.c
	mpi-io/read_orde.c
	mpi-io/write_orde.c
	adio/common/ad_init.c
	adio/common/ad_end.c
	adio/common/ad_seek.c
	adio/common/stats_setb.c
	adio/ad_xfs/ad_xfs_seek.c
- adio/common/ad_write_coll.c: assign *error_code even #if
  PRINT_ERR_MSG so that the compiler doesn't complain about the unused
  argument.
- adio/ad_xfs/ad_xfs_open.c: changed old_umask to be of type (unsigned
  int). 
- adio/ad_nfs/ad_nfs_open.c: changed old_umask to be of type (unsigned
  int). 
- adtion/common/ad_write_coll.c: changed some while(1) statements to
  while(!done) to silence picky compiler warnings.
- Changed configure.in, aclocal.m4, configure (since we can't run
  autoconf) and adio/common/as_fstype.c to properly check for struct
  statfs.f_fstypename on Linux and BSD systems instead of relying on
  some compiler predefined preprocessor macro.  The previous approach
  didn't work on OpenBSD 2.8.
- Changed configure.in/configure -- the line reading:
        CFLAGS="$CFLAGS -g -std1 -warnprotos -verbose -DAIO_PRIORITY_DEFAULT"
  to
        CFLAGS="$CFLAGS -g -verbose -DAIO_PRIORITY_DEFAULT"
  because it is not a valid assumption that on Alpha architectures you
  will alsways be compiling with the alpha compilers.
