+LZO -- a real-time data compression library
+============================================================================
+
+LZO is free of any known bugs.
+
+Nevertheless LZO has been reported to break the optimizer of some
+compilers including gcc 2.7.2 (AIX, IRIX) and Watcom C 9.5.
+
+So if `lzotest' reports data decompression errors you should recompile
+everything without optimizations and see if that fixes the problem.
+I'd like to hear about optimizer problems and possible workarounds.
+
+
+Known compiler problems:
+------------------------
+ some versions of gcc use `-O2 -fno-strength-reduce'
+ some versions of gcc use `-O2 -fno-schedule-insns -fno-schedule-insns2'
+ Watcom C 9.5 compile with `-oneax' instead of `-oneatx'
