+   Part of testsuite for libm.
+
+   This file has to be included by a master file that defines:
+
+   Makros:
+   FUNC(function): converts general function name (like cos) to
+   name with correct suffix (e.g. cosl or cosf)
+   MATHCONST(x):   like FUNC but for constants (e.g convert 0.0 to 0.0L)
+   MATHTYPE:       floating point type to test
+   TEST_MSG:       informal message to be displayed
+   CHOOSE(Clongdouble,Cdouble,Cfloat):
+   chooses one of the parameters as epsilon for testing
+   equality
+   PRINTF_EXPR     Floating point conversion specification to print a variable
+   of type MATHTYPE with printf. PRINTF_EXPR just contains
+   the specifier, not the percent and width arguments,
+   e.g. "f"

+/* This program isn't finished yet.
+   It has tests for acos, acosh, asin, asinh, atan, atan2, atanh,

+   frexp, ldexp,

+   pow, sin, sinh, tan, tanh, fabs, hypot.
+   Tests for the other libm-functions will come later.
+
+   The routines using random variables are still under construction. I don't
+   like it the way it's working now and will change it.
+
+   Exception handling has not been implemented so far so don't get fooled
+   that these tests pass.

+   Parameter handling is primitive in the moment:
+   --verbose=[0..3] for different levels of output:
+   0: only error count
+   1: basic report on failed tests
+   2: full report on failed tests
+   3: full report on failed and passed tests (default)
