  64 # Notes:
  65 #   Currently builds with gcc 3.3 for i386, arm, mips, mipsel.
  66 #   Only tested with multilib enabled.
  67 #   For i386, long double is the same as double (64 bits).  While this
  68 #      is unusual for x86, it seemed the best approach considering the
  69 #      limitations in the gcc floating point emulation library.
  70 #   For arm, soft float uses the usual libfloat routines.
  71 #   The uClibc built will support _only_ applications compiled with the
  72 #      -msoft-float flag.  To avoid CFLAGS problems, you may want to use
  73 #      scripts similar to those in the build*/staging_dir/bin directory.
