#include "config.h"
New file. * plug-ins/makefile.msc: New file. * plug-ins/*/*.c (Well, not really all files, but many): Portability fixes. Include config.h, and guard inclusion of POSIX and Unix headers like <unistd.h>, <dirent.h> and <sys/time.h>. Include <string.h> if functions from it are used. Use g_ntohl() and g_htonl() insteead of ntohl() and htonl(), thus no need to include <netinet/in.h>. Include <io.h> on Win32 when using open/read/write (which actually are defined as _open/_read/_write by glib.h). Define S_* macros if necessary on Win32. Define rint() and M_PI if necessary (these definitions should be factored out somewhere, no sense repeating them in lots of files). Open files in binary mode when needed. * plug-ins/FractalExplorer/FractalExplorer.c: Use g_malloc()/g_free(). Use g_strdup_printf(). * plug-ins/dbbrowser/dbbrowser.c: No need to include <X11/Xlib.h>. * plug-ins/destripe/destripe.c: Guard use of SIGBUS. * plug-ins/{flame/flame,hrz/hrz,pnm/pnm}.c: No need to check for NULL returns from g_malloc() and g_new() as they abort on failure. Use g_strdup_printf(). * plug-ins/gz/gz.c: Win32 version of running the subprocess. * plug-ins/hrz/hrz.c: Win32 version. Use more generic tests for non-Unix (OS/2 and Win32), for instance HAVE_MMAP. * plug-ins/script-fu/interp_slib.c: Win32 version of myruntime(). * plug-ins/script-fu/interp_sliba.c: Handle \\ (escaped backslahsh). * plug-ins/script-fu/script-fu-console.c: Bypass on Win32. * plug-ins/script-fu/script-fu-scripts.c: Portability fixes. Use g_strdup_printf() instead of separate malloc() and sprintf(). Use g_strescape() for strings being passed to Scheme. Some Win32-only stuff.

Changed plug-in menu registration again to allow passing just the menu 2004-05-07 Michael Natterer <mitch@gimp.org> Changed plug-in menu registration again to allow passing just the menu item's label (not the full path) in gimp_install_procedure() and only the path (excluding the item's label) in gimp_plugin_menu_register(). Matches the internal action system better and makes translating the menu paths much easier. (Of yourse it's still possible to use the old syntax for backward compatibility). * app/plug-in/plug-in-proc.[ch]: added "gchar *menu_label". * app/plug-in/plug-in-params.[ch]: added new functions plug_in_param_defs_check() and plug_in_proc_args_check() which check if a procedure's parameters match its menu location (e.g. <Image> needs RUN-MODE, IMAGE, DRAWABLE). * app/plug-in/plug-in-message.c (plug_in_handle_proc_install): if registering an old-style (full) menu_path, use plug_in_param_defs_check(), set proc_def->menu_label otherwise. * tools/pdbgen/pdb/plug_in.pdb (plugin_menu_register): use plug_in_proc_args_check() on the passed menu_path and make sugre old and new style menu registration are not mixed. * app/pdb/plug_in_cmds.c: regenerated. * app/plug-in/plug-in-rc.c: save/restore "menu_label". * app/actions/file-dialog-actions.c * app/actions/plug-in-actions.c * app/menus/plug-in-menus.c: changed action/menu creation accordingly. Some hacks needed to allow both old and new style menu_label/menu_paths. * app/plug-in/plug-in.c * app/widgets/gimpfiledialog.c * app/xcf/xcf.c: changed accordingly. * plug-ins/common/align_layers.c * plug-ins/common/animationplay.c * plug-ins/common/animoptimize.c * plug-ins/common/apply_lens.c * plug-ins/common/autocrop.c * plug-ins/common/autostretch_hsv.c * plug-ins/common/blinds.c * plug-ins/common/blur.c * plug-ins/common/borderaverage.c * plug-ins/common/bumpmap.c * plug-ins/common/c_astretch.c * plug-ins/common/ccanalyze.c * plug-ins/common/channel_mixer.c * plug-ins/common/checkerboard.c * plug-ins/common/color_enhance.c * plug-ins/common/colorify.c * plug-ins/common/colortoalpha.c * plug-ins/common/compose.c * plug-ins/common/convmatrix.c * plug-ins/common/cubism.c * plug-ins/common/curve_bend.c * plug-ins/common/decompose.c * plug-ins/common/deinterlace.c * plug-ins/common/depthmerge.c * plug-ins/common/destripe.c * plug-ins/common/diffraction.c * plug-ins/common/displace.c * plug-ins/common/edge.c * plug-ins/common/emboss.c * plug-ins/common/engrave.c * plug-ins/common/exchange.c * plug-ins/common/film.c * plug-ins/common/flarefx.c * plug-ins/common/fractaltrace.c * plug-ins/common/screenshot.c: ported the first few plug-ins to the new registration scheme.
