You need GNU make. On HP-UX, you also need GNU sed.

- - Linux/x86, gcc-2.95.x, gcc-3.0(pre)
- - Linux/ia64, gcc-2.96, gcc-3.0(pre)
- - Linux/arm, gcc-2.95.3

-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"

+won't work at all.
+
+If you use g++ on OSF/1 or Tru64 using gcc-3.0.n with n larger than 1, you
+should not add -fno-exceptions to the CXXFLAGS, since that will generate
+wrong code (gcc-3.1 is okay again, as is gcc-3.0).
