[svn-r1117] Changes since 19990303
---------------------- ./configure.in ./configure [REGENERATED] The path for a command is calculated explicitly the hard way because `type -path' isn't portable. ./config/freebsd ./config/linux-gnu ./config/linux-gnulibc2 Changed the way files reference each other. ./config/gnu-flags [NEW] ./config/dec-flags [NEW] These files figure out what flags to pass to certain compilers so we can reuse code in more than one config/* file. They also have better warning messages when old compilers are used. ./config/linux-gnulibc1 ./config/dec-osf4.x These files use the new *-flags files. ./src/H5D.c ./src/H5Onull.c ./src/H5Tconv.c ./tools/h5ls.c Fixed a compiler warning. ./src/H5detect.c Added a better comment to the top of the generated file.
