-Building XEmacs requires about 41 Mb of disk space (including the
-XEmacs sources). Once installed, XEmacs occupies about 16 Mb in the
-file system where it is installed; this includes the executable files,
-Lisp libraries, miscellaneous data files, and on-line documentation.
-The amount of storage of the Lisp directories may be reduced by
-compressing the .el files. If the building and installation take place
-in different directories, then the installation procedure temporarily
-requires 41+16 Mb. Adjust this value upwards depending upon what
-additional Lisp support is installed.
+ Verify that your users have a high enough stack limit. On some
+ systems such as OpenBSD and OSF/Tru64 the default is 2MB which is
+ too low. See 'PROBLEMS' for details.

+Building XEmacs requires about 100 Mb of disk space (including the
+XEmacs sources). Once installed, XEmacs occupies between 20 and 100 Mb
+in the file system where it is installed; this includes the executable files,
+Lisp libraries, miscellaneous data files, and on-line documentation. The
+exact amount depends greatly on the number of extra lisp packages that are
+installed
