+Unfortunately, later releases of Cygnus-released compilers (not the
+Net-released ones) have a bug with the same `problem signature'.
+
+If you're lucky, you'll get an error while compiling that looks like:
+
+event-stream.c:3189: internal error--unrecognizable insn:
+(insn 256 14 15 (set (reg/v:SI 24)
+ (minus:SI (reg/v:SI 25)
+ (const_int 2))) -1 (insn_list 11 (nil))
+ (nil))
+ 0 0 [main]
+
+If you're unlucky, your code will simply execute incorrectly.
+
+*** Don't use gcc-2.95.2 with -mcpu=ultrasparc on Solaris 2.6.
+
+gcc will assume a 64-bit operating system, even though you've
+merely told it to assume a 64-bit instruction set.
