Which I think is not what the documentation says.

Removes double (( )) to make DEBUG_PRINT compatible with real function calls.
Change the name to DPRINTF to be consistent with other DPRINTF macros
throughout qemu.
Include the "RTL8139: " prefix in the macro. This changes some debug output
slightly since the prefix wasn't present on all lines.

Part of the change was done using the "coccinelle" tool with the following
small semantic match:
    @@ expression E; @@

    - DEBUG_PRINT((E))
    + DPRINTF(E)

The REG_PC constant used in the ARM nwfpe code is fine in the kernel
but when used in qemu can clash with a definition in the host system
include files (in particular on Ubuntu Lucid SPARC, including signal.h
will define a REG_PC). Rename the constant to avoid this issue.

With softfloat it's not possible to play with the overflow of an
unsigned value to get the 0 case partially correct. Use a special case
for that. Using a division to generate an infinity is the easiest way
that works for both softfloat and softfloat-native.

float*_scalnb() were not taking into account all cases. This patch fixes
some corner cases:
- NaN values in input were not properly propagated and the invalid flag
  not correctly raised. Use propagateFloat*NaN() for that.
- NaN or infinite values in input of floatx80_scalnb() were not correctly
  detected due to a typo.
- The sum of exponent and n could overflow, leading to strange results.
  Additionally having int16 defined to int make that happening for a very
  small range of values. Fix that by saturating n to the maximum exponent
  range, and using an explicit wider type if needed.

The floatx80 format uses an explicit bit that should be taken into account
when converting to and from commonNaN format.

When converting to commonNaN, the explicit bit should be removed if it is
a 1, and a default NaN should be used if it is 0.

When converting from commonNan, the explicit bit should be added.
