+   contain very large "case statements" (over 100 cases) that on some

+   these files usually take less then 10 seconds to compile. For 64bit
+   systems using gcc the problem appears to be much worse.
+
+   The two files with the large number of cases, remote.c and x11vnc.c,
+   have no real need to be optimized (the code is used only very
+   infrequently). So it is fine to supply "-O0" (disables optimization)
+   to CFLAGS when compiling them. However, it is tricky with
+   autoconf/automake to do this (especially since both the compiler and
+   make versions have a big effect).
+
+   So if the compile times are getting too long for you for these two
+   files you will need to manually change some things. First, run
+   configure and when it has finished, edit the generated file
+   x11vnc/Makefile and put these lines at the very top:
+x11vnc-x11vnc.o :  CFLAGS += -O0
+x11vnc-remote.o :  CFLAGS += -O0
+
+   Those lines assume gnu make (gmake) is being used. If you are using
+   another make, say Solaris make, insert these instead:
+x11vnc-x11vnc.o := CFLAGS += -O0
+x11vnc-remote.o := CFLAGS += -O0
+
+   You could write a build shell script that modified the Makefile this
+   way before running make.
+
+   The "-O0" (note it is "capital Oh" followed by "zero") assumes the gcc
+   compiler. If you are using a different compiler you will need to find
+   the command line option to disable optimization, or otherwise have the
+   lines set CFLAGS to the empty string.
