# SYNOPSIS
#
#   AX_F90_HEADER(HEADER, HEADER-REGEXP, FUNCTION-BODY [, SEARCH-PATH [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
#   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).
