If `--with-gtk', `--with-gnome', or `--with-msw' are used or implied, treat
component options as Bool. The `lucid' widgets are a homebrew set, emulating
Motif but faster. Lucid toolbars, menubars, and scrollbars are implemented
-in Xt. Lucid dialogs and misc widgets wrap and enhance Athena (maybe Motif;
-platform-dependent). Several enhanced (eg, 3d) Athena libraries may be used,
+in Xt. Lucid dialogs and misc widgets wrap and enhance Motif (or Athena if
+Motif is not found). Several enhanced (eg, 3d) Athena libraries may be used,
but the default is the X11R6 `libXaw' (flat) widgets. Use `--with-athena' to
explicitly specify which library to link against.
--with-menubars=TYPE (Enum) Types: `lucid'(*), `motif', or `no'.
*WARNING* The Motif menubar is currently broken.
--with-scrollbars=TYPE (Enum) Types: `lucid'(*), `motif', `athena', or `no'.
---with-dialogs=TYPE (Enum) Types: `motif'(*), `lucid'(*), `athena', or `no'.
---with-widgets=TYPE (Enum) Types: `motif'(*), `lucid', `athena', or `no'.
+--with-dialogs=TYPE (Enum) Types: `lucid'(*), `motif', `athena', or `no'.
+--with-widgets=TYPE (Enum) Types: `lucid', `motif', `athena', or `no'(*).
--with-athena=TYPE (Enum) Link with the TYPE Athena library. Types:
`xaw' [flat], `3d', `next', `95', or `xpm'.
--with-dragndrop (*) Support generic drag and drop API. (EXPERIMENTAL)
it in the standard C library.
--with-system-malloc (Bool) Use the system malloc, instead of GNU malloc.
--with-debug-malloc (Bool) Use the debugging malloc package.
+--use-regex-malloc=no (Bool) Use malloc (not alloca) for regex fail stack.
+ Setting this to 'no' allows crashes - it may be
+ impossible to detect stack exhaustion, and your
+ XEmacs will crash.
