+ Hints: Forcing 32-bit build:
+ * CFLAGS="-m32 -g -O2" ./configure
+
+ Forcing 64-bit build:
+ * CFLAGS="-m64 -g -O2" ./configure
+
+ Forcing a 32-bit build with 386 backward compatibility:
+ * CFLAGS="-m32 -g -O2" ./configure --host=i386-pc-linux-gnu
+
+ Forcing a 32-bit build for Sparcv9 (typical for Sparc v9)
+ * CFLAGS="-m32 -Wa,-Av9a -g -O2" ./configure

+ARCHITECTURES SUPPORTED
+-----------------------
+
+Currently, x86 (i386, i486, i586, i686), x86 64-bit, PowerPC 32/64, S390, S390x
+and Sparcv9 32/64 are supported. Only tested on Linux so far, but should
+theoretically work on other operating systems.
