Howto build with debugging symbols?

[Dmitri Trembovetski]

   Hi Regina,

   set FASTDEBUG=true to enable debug symbols (with compiler
   optimizations enabled), or DEBUG=true to get a build with
   compiler opt. disabled (and I believe a debug runtime will
   be used on windows in this case as well).

   I recommend using FASTDEBUG=true - the resulting binaries
   are much faster than DEBUG and are useful for most
   debugging applications.

   You can also mix and match optimized and fastdebug binaries.

   Suppose you have an optimized build - you can then
   rebuild part of the workspace with FASTDEBUG so that
   only some libs will be recompiled with debug symbols
   (there are some exceptions to this, but mostly it should
   work).

   For example,
    #> cd jdk/make/sun/awt
    #> gnumake FASTDEBUG=true
   will build awt libraries with debug symbols, while the rest
   of the binaries will be optimized.

   Thanks,
     Dmitri
