[svn-r1149] ./configure.in

./configure		[REGENERATED]
./src/H5config.h.in	[REGENERATED]
./src/H5private.h
	Temporarily commented out the code that tries to link a simple
	MPI-IO application because I'm not sure how to pass $LDFLAGS
	and $LIBS to the compiler.

	Removed the `--enable-parallel=ibm' switch because the library
	we link with is either -lmpcc or -lmpcc_r but not both. The
	only way to tell is to see what compiler was specified (mpcc
	or mpcc_r) but if that compiler is specified then we don't
	need any libraries (the compiler script supplies them). That
	leaves just two choices: the user must use a compiler script:

	    CC=mpcc ./configure

	or the user must state which library is desired:

	    LDFLAGS='-lmpcc' ./configure --enable-parallel

	Checks for <setjmp.h>, longjmp(), and signal(). We don't check
	for setjmp() because it could be a macro (in fact, Posix
	requires it to be a macro) and if longjmp() is present then
	setjmp() is probably present too ;-)

./src/H5detect.c
	The alignment detection loop uses SIGBUS and setjmp/longjmp
	instead of fork/wait in order to get around bugs with forking
	in conjunction with mpich.  This hasn't been tested on the
	SP-2 yet but it does work on the DEC Alpha.

./test/Makefile.in
./testpar/Makefile.in
./tools/Makefile.in
	Changed the order that libraries are linked so -lhdf5 is
	always before $LDFLAGS.
