            # Notes:
            # 1. Do not remove/modify these flags or their order before either
            # asking the project leads at
            # http://www.opensolaris.org/os/project/ksh93-integration/
            # These flags all have a purpose, even if they look
            # weird/redundant/etc. at the first look.
            #
            # 2. We use -KPIC here since -Kpic is too small on 64bit sparc and
            # on 32bit it's close to the barrier so we use it for both 32bit and
            # 64bit to avoid later suprises when people update libast in the
            # future
            #
            # 3. "-D_map_libc=1" is needed to force map.c to add a "_ast_" prefix to all
            # AST symbol names which may otherwise collide with Solaris/Linux libc
            #
            # 4. "-DSHOPT_SYSRC" enables /etc/ksh.kshrc support (AST default is currently
            # to enable it if /etc/ksh.kshrc or /etc/bash.bashrc are available on the
            # build machine).
            #
            # 5. -D_lib_socket=1 -lsocket -lnsl" was added to make sure ksh93 is compiled
            # with networking support enabled, the current AST build infratructure has
            # problems with detecting networking support in Solaris.
            #
            # 6. "-xc99=%all -D_XOPEN_SOURCE=600 -D__EXTENSIONS__=1" is used to force
            # the compiler into C99 mode. Otherwise ksh93 will be much slower and lacks
            # lots of arithmethic functions.
            #
            # 7. "-D_TS_ERRNO -D_REENTRANT" are flags taken from the default OS/Net
            # build system.
            #
            # 8. "-xpagesize_stack=64K is used on SPARC to enhance the performace
            #
            # 9. -DSHOPT_CMDLIB_BLTIN=0 -DSH_CMDLIB_DIR=\\\"/usr/ast/bin\\\" -DSHOPT_CMDLIB_HDR=\\\"/home/test001/ksh93/ast_ksh_20070322/solaris_cmdlist.h\\\"
