ax_f90_header

Set up the compiler flags to use a given fortran 90 header. HEADER is the name of the header. HEADER-REGEXP is a regular expression (used by find) matched by the filename of the header. FUNCTION-BODY is the body of a function (including the 'use' statement and the call to a function defined by the module) SEARCH-PATH is a colon-separated list of directories that will be recursively searched for header files. If empty, the search path will be composed of $prefix, $ac_default_prefix, and all directories exactly one level *above* the directories in $LD_LIBRARY_PATH (the rationale is that when libraries are put in /some/path/lib, the headers are often put in a directory like /some/path/include). An output variable named F90_HEADER_xxx will be set up with the proper flag for substitution in Makefiles (xxx is built from the first argument, with autoconf traditional escapes).
