+Sun 3, Sun 4 (sparc), Sun 386 (m68k-sun-sunos, sparc-sun-sunos, i386-sun-sunos,
+ sparc-sun-sunos4.1.3noshr, sparc-sun-solaris2.*,
+ i386-sun-solaris2.*, sparc*-*-linux-gnu)
+
+ To build a 64-bit Emacs (with larger maximum buffer size and
+ including large file support) on a Solaris system which supports
+ 64-bit executables, use the Sun compiler, configuring something like
+ this (see the cc documentation for information on 64-bit
+ compilation): env CC="cc -xarch=v9" ./configure
+
+ As of version 2.95, GCC doesn't support the 64-bit ABI properly, but
+ later releases may.
+
+ Some versions of Solaris 8 have a bug in their XIM (X Input Method)
+ implementation which causes Emacs to dump core when one of several
+ frames is closed. To avoid this, either install patch 108773-12
+ (for Sparc) or 108874-12 (for x86), or configure Emacs with the
+ `--with-xim=no' switch (you can use Leim input methods instead).
+
+ On Solaris 2.7, building Emacs with WorkShop Compilers 5.0 98/12/15
+ C 5.0 failed, apparently with non-default CFLAGS, most probably due to
+ compiler bugs. Using Sun Solaris 2.7 Sun WorkShop 6 update 1 C
+ release was reported to work without problems. It worked OK on
+ another system with Solaris 8 using apparently the same 5.0 compiler
+ and the default CFLAGS.
+
+ Emacs 21.1 and 21.2 built with Sun's ProWorks PC3.0.1 compiler on
+ Intel/Solaris 8 was reported to abort and dump core during startup.
+ Using GCC or a newer SUN compiler (Sun WokShop 6 update 2 C 5.3
+ 2001/05/15) solves the problem.
+
+ Emacs 20.5 and later work on SPARC GNU/Linux with the 32-bit ABI.
+ As of release 2.95, GCC doesn't work properly with the 64-bit ABI
+ (applicable on UltraSPARC), but that isn't the default mode.
+
+ Emacs 20.3 fails to build on Solaris 2.5 if you use GCC 2.7.2.3.
+ Installing GCC 2.8 fixes the problem.
+
+ 19.32 works on Solaris 2.4 and 2.5. On Solaris 2.5
+ you may need one of these patches to prevent Emacs from crashing
+ when it starts up:
+ 103093-03: [README] SunOS 5.5: kernel patch (2140557 bytes)
+ 102832-01: [README] OpenWindows 3.5: Xview Jumbo Patch (4181613 bytes)
+ 103242-04: [README] SunOS 5.5: linker patch (595363 bytes)
+
+ There are reports that using SunSoft cc with -xO4 -xdepend produces
+ bad code for some part of Emacs.
+
+ Emacs works ok Sunos 4.1.x
+ provided you completely replace your C shared library
+ using one of the SunOS 4.1.x jumbo replacement patches from Sun.
+ Here are the patch numbers for Sunos 4.1.3:
+ 100890-10 SunOS 4.1.3: domestic libc jumbo patch
+ 100891-10 SunOS 4.1.3: international libc jumbo patch
+
+ Some people report that Emacs crashes immediately on startup when
+ used with a non-X terminal, but we think this is due to compiling
+ with GCC and failing to use GCC's "fixed" system header files.
+
+ Some Sun versions of X windows use the clipboard, not the selections,
+ for transferring text between clients. The Cut, Paste and Copy items
+ in the menu bar Edit menu work with the clipboard.
