In order to support, some core modules are modified as follows: core/sys/dsc.h - If CTK_CONF_ICONS is diabled, the whole icon-related code is disabled. - DSC_HEADER is changed to remove extra semicolon. core/sys/process.h - process_data_t is expressed by void* in signatures (known bug on sdcc). core/sys/autostart.h - autostart_processes is changed to remove extra semicolon. core/sys/cc.h - CC_CONF_ASSIGN_AGGREGATE is introduced. - CC_CONF_INC_CAST_POINTER is introduced, a workaround of a kind of sdcc bug for an increment. core/net/hc.c core/net/uip_arp.c core/net/uaodv.c - Aggregation assignments are changed to uip_ipaddr_copy. core/net/psock.c core/net/uipbuf.c core/net/dhcpc.c apps/shell/shell.c core/ctk/vnc-server.c core/ctk/vnc-out.c - "register" keyword in a signature cannot be used in sdcc, CC_REGISTER_ARG is used instead. core/net/uip-over-mesh.c - An extra semicolon is removed. apps/dhcp/dhcp-dsc.c apps/shell/shell-dsc. apps/ftp/ftp-dsc.c apps/process-list/process-list-dsc.c apps/email/email-dsc.c apps/webserver/webserver-dsc.c apps/vnc/vnc-dsc.c apps/vnc/vnc-viewer.h apps/webbrowser/www-dsc.c apps/about/about-dsc.c apps/irc/irc-dsc.c apps/telnet/telnet-dsc.c apps/telnetd/telnetd-dsc.c apps/netconf/netconf-dsc.c apps/directory/directory-dsc.c pps/calc/calc-dsc.c - Modify an extern type to a real declaration, which is static to prevent a compile error. core/net/mac/xmac.c - Variables cannot be defined in a head of block on sdcc. core/ctk/ctk.h core/ctk/ctk.c apps/program-handler/program-handler.c - If CTK_CONF_ICONS is diabled, the whole icon-related code is disabled. Makefile.include - Add a set of configuration for an assembler. - $(CLEAN) variable is introduced for customized cleanup. apps/process-list/process-list.c - PROCESSLIST_CONF_HEIGHT is introduced to address smaller screen size. core/lib/ctk-filedialog.c - FILES_CONF_HEIGHT is introduced to address smaller screen size. - "register" keyword in a signature cannot be used in sdcc, CC_REGISTER_ARG is used instead. apps/vnc/vnc-viewer.c - A cast is added to prevent a compile error. - "register" keyword in a signature cannot be used in sdcc, CC_REGISTER_ARG is used instead. apps/webbrowser/webclient.c - CC_CONF_INC_CAST_POINTER is introduced, a workaround of a kind of sdcc bug for an increment. core/loader/elfloader.c - A cast is added to prevent a compile error. core/net/rime/rimeaddr.c - An initialization is added to prevent a compile error. core/net/rime/rudolph0.c - NULL is changed to 0, because NULL causes a compile error. core/net/rime/route-discovery.c - Add an argument to match the definition of nf_callbacks. cpu/z80/strcasecmp.h cpu/z80/strcasecmp.c cpu/z80/contiki-sdcc-conf.h cpu/z80/mtarch.c cpu/z80/mtarch.h cpu/z80/Makefile.z80 - New files to make compilation availble on sdcc. - Added support for multithreading.
