# SYNOPSIS
#
#   MHD_CHECK_FUNC_GETTIMEOFDAY([ACTION-IF-AVAILABLE],
#                               [ACTION-IF-NOT-AVAILABLE])
#
# DESCRIPTION
#
#   This macro checks for presence of gettimeofday() function.
#   If function is available macro HAVE_GETTIMEOFDAY is defined
#   automatically.
#
#   Example usage:
#
#     MHD_CHECK_FUNC_GETTIMEOFDAY([var_use_gettimeofday='yes'])
#
#   The cache variable used in check so if any test will not work
#   correctly on some platform, user may simply fix it by giving cache
#   variable in configure parameters, for example:
#
#     ./configure mhd_cv_func_memmem_have=no
#
#   This simplifies building from source on exotic platforms as patching
#   of configure.ac is not required to change results of tests.
