 You need GNU make. On HP-UX, you also need GNU sed.
 
 Known to work with:
-  - Linux/x86, gcc-2.7.0, gcc-2.7.2, gcc-2.8.0, egcs-1.1
-  - Solaris 2.4 (sparc), gcc-2.7.0, gcc-2.7.2, egcs-1.1
-  - OSF/1 V4.0 (alpha), egcs-1.1
-  - Irix 5.3, CC 4
-
-The "make" step takes about 4 hours, on a 486 DX / 33 MHz / 8 MB.
-
-On Linux, g++ needs 15 MB to compile the tests. So better have
-17 MB swap space and 1 MB room in $TMPDIR.
-
-If you use gcc and g++ version 2.7.x, don't add -O2 to the CXXFLAGS, because
-"g++ -O" generates better code for libcln.a than "g++ -O2".
-
-If you use g++ version 2.8.x or egcs-2.91.x (a.k.a. egcs-1.1) or gcc-2.95.x,
-I recommend adding "-fno-exceptions" to the CXXFLAGS. This will likely
-generate better code.
-
-If you use g++ version egcs-2.91.x (egcs-1.1) or gcc-2.95.x on Sparc, add
-either "-O" or "-O2 -fno-schedule-insns" to the CXXFLAGS. With full "-O2",
-g++ miscompiles the division routines. Also, for --enable-shared to work, you
-need egcs-1.1.2 or newer.
-
-On MIPS (SGI Irix 6), pass option "--without-gmp" to configure. gmp does
-not work when compiled in "n32" binary format on Irix.

+The "make" step takes about 1 hour, on a P-II / 400 MHz / 64 MB.
+
+If you use g++ gcc-2.95.x or gcc-3.0, I recommend adding "-fno-exceptions" 
+to the CXXFLAGS. This will likely generate better code.
+
+If you use g++ from gcc-2.95.x on Sparc, add either "-O", "-O1" or
+"-O2 -fno-schedule-insns" to the CXXFLAGS. With full "-O2", g++ miscompiles
+the division routines. If you use g++ older than 2.95.3 on Sparc you should
+also specify --disable-shared because of bad code produced in the shared
+library. Also, on OSF/1 or Tru64 using gcc-2.95.x, you should specify
+--disable-shared because of linker problems with duplicate symbols in shared
+libraries.
