-/*
- * ieeetest.c --- test IDCT code against the IEEE Std 1180-1990 spec
- *
- * Note that this does only one pass of the test.
- * Six invocations of ieeetest are needed to complete the entire spec.
- * The shell script "doieee" performs the complete test.
- *
- * Written by Tom Lane (tgl@cs.cmu.edu).
- * Released to public domain 11/22/93.
