[svn-r16305] Description:
Add detection of C99 "designated initializers" to configure script and
use new H5_HAVE_C99_DESIGNATED_INITIALIZER macro to conditionally compile
default layout variables in src/H5Pdcpl.c
Also, minor code cleanups, etc.
Tested on:
FreeBSD/32 6.3 (duty) in debug mode
FreeBSD/64 6.3 (liberty) w/C++ & FORTRAN, in debug mode
Linux/32 2.6 (jam) w/PGI compilers, w/C++ & FORTRAN, w/threadsafe,
in debug mode
Linux/64-amd64 2.6 (smirom) w/Intel compilers w/default API=1.6.x,
w/C++ & FORTRAN, in production mode
Linux/64-ia64 2.6 (cobalt) w/Intel compilers, w/C++ & FORTRAN,
in production mode
Linux/64-ia64 2.4 (tg-login3) w/parallel, w/FORTRAN, in production mode
Linux/64-amd64 2.6 (abe) w/parallel, w/FORTRAN, in production mode
Mac OS X/32 10.5.6 (amazon) in debug mode
Mac OS X/32 10.5.6 (amazon) w/C++ & FORTRAN, w/threadsafe,
in production mode
