+ Hints: Forcing 32-bit build:
+ * CFLAGS=-m32 ./configure
+
+ Forcing 64-bit build:
+ * CFLAGS=-m64 ./configure
+
+ Forcing a 32-bit build with down to 386 compatibility:
+ * CFLAGS=-m32 ./configure --target=i386-pc-linux-gnu

+ARCHITECTURES SUPPORTED
+-----------------------
+
+Currently, x86 (i386, i486, i586, i686), x86 64, PowerPC 32/64 and S390 are
+supported. The current use of sys_futex() makes it Linux-dependent, although
+this portability limitation might go away in a near future by using the pthread
+cond vars.
