[svn-r3892] Purpose:
Better Mouse Trap^W^WBug Fix Description: Instead of having the large file support stuff be in the config/gnu-flags directory, I added it to the configure.in file so that it first checks for the syscall ``getdents64()''. If it finds it, then it removes the ``-malign-double'' flag if the GCC compiler is 2.95.x since this flag doesn't play well with the LFS stuff. Solution: Added test for getdents64(), if found it removes the -malign-double flag if the compiler is 2.95.x. This is done in the configure.in file. The gnu-flags file is returned to normal. A new field is added to the H5config.h.in file because of the getdents64 check. Platforms tested: Linux
