changes. The two Big Changes are elegance (much more re-use of code rather than cut-n-pasting the same code over and over and over and...) and enabling cross-compilation for F77 and F90 (because we actually have to *run* some compiled F77 and F90 programs for some of the tests, which obviously won't work in a cross-compilation environment -- so enable the use of config.cache to load such values in cross-compiling environments). This commit was SVN r8991.
