+Problems with known work-a-rounds:
+
+    * There is a bug in gcc-2.95 that causes calc, when compiled with -O2,
+      to fail the regression test.  The work-a-round is to compile with -O
+      or to use gcc-2.96 or later.

+    * Solaris cc somtimes barfs while compiling zrand.c.  In particular, calc
+      barfs on on the SVAL macro.  The work-a-round is to use the Solaric cc
+      Makefile set sets -DFORCE_STDC.  I.e,:
+
+	    CCWARN=
+	    CCOPT= ${DEBUG} ${NO_SHARED}
+	    CCMISC= -DFORCE_STDC

+	    ILDFLAGS=
+	    #
+	    LCC= cc
+	    CC= ${PURIFY} ${LCC}
+
+    * There is a bug in some versions of the Dec/Compaq cc for the Alpha
+      where the following:
+
+	    #include <stdio.h>
+	    #define SVAL(a,b) (unsigned long)(0x ## a ## b ## ULL)
+	    main(){SVAL(b8a8aeb0,8168eadc);}
+
+      fails because it puts a space inside the concatenated hex.  Calc
+      has code that is affected by this bug.  This bug has been reported
+      to Compaq and may be fixed in the future.	 A work-a-round is to
+      compile with cc -std0 or to use a later version of their compiler.
+
+    * On a Digital UNIX V4.0F (Rev. 1229) on a 500 Mhz 21264, make check
+      dies a horrible death starting in test 600 and 622 gives 100s of
+      messages for calc version 2.11.0t9.4 using the Dec's cc with -O2:

+	**** t4 != a4: 622: algcheck 1
+	...
+
+	it finally hangs at test 2000.
+
+      The work-a-round is to compile calc without the optimizer.  If this
+      happens to you, try compiling without -O and without -O2.	 I.e., in
+      the Makefile, set:
+
+	DEBUG= -g
+
+    * The sparcv9 support for 64 bit Solaris under gcc-2.96 is able
+      to compile calc, but calc dumps core very early on in startup.
+      It is said that sparcv9 support in gcc-2.96 is very unofficial.
+      There is no work-a-round for this compiler problem.
