+Tested tool versions
+--------------------
+
+In order to compile QEMU succesfully, it is very important that you
+have the right tools. The most important one is gcc. I cannot guaranty
+that QEMU works if you do not use a tested gcc version. Look at
+'configure' and 'Makefile' if you want to make a different gcc
+version work.

+[1] On Alpha, QEMU needs the gcc 'visibility' attribute only available
+    for gcc version >= 3.3.
+[2] Linux >= 2.4.20 is necessary for precise exception support
+    (untested).

+[4] gcc 2.95.x generates invalid code when using too many register
+variables. You must use gcc 3.x on PowerPC.
