Jerry, With the latest round of changes to configure.ac, the 21.5 configure script gets confused on my home machine and thinks that FOR_MSW should be set. Here is the failure: gcc -c -Wall -Wno-switch -Wundef -Wsign-compare -Wno-char-subscripts -Wpacked -Wunused-parameter -g -Demacs -I. -I/home/acs/xemacs-21.5-2006-03-28/src -DHAVE_CONFIG_H -I/usr/X11R6/include balloon-x.c In file included from console-x.h:51, from console-x-impl.h:39, from balloon-x.c:28: /usr/include/X11/xpm.h:71:63: error: simx.h: No such file or directory make[1]: *** [balloon-x.o] Error 1 make[1]: Leaving directory `/home/acs/xemacs-21.5-2006-03-28/src' make: *** [src] Error 2 This failure is caused by this difference in src/config.h: /* Compile in support for X pixmaps via the `xpm' library? */ #define HAVE_XPM 1 -/* #undef FOR_MSW */ +#define FOR_MSW 1 /* Compile in support for "X faces" via the `compface' library?

Configuring --with-msw=no has no effect. Please let me know if any more information is needed. Thanks, Vin
