Solaris build failure

[rstub]

I have incorporated the PCG family into an R package. On submission to CRAN I have been informed about a compilation error on Solaris:

In file included from dqrng.cpp:22:0:
../inst/include/pcg_random.hpp:1639:18: error: reference to ‘extended’ is ambiguous
using ext_std8 = extended<table_pow2, advance_pow2, BaseRNG,
^

from dqrng.cpp:18:
/usr/include/floatingpoint.h:71:18: note: candidates are: typedef unsigned int extended [3]
typedef unsigned extended[3];
^

I was able to circumvent this with a simple patch to use fully qualified names. Are you interested in a PR based on this patch?

Can confirm on:

$ uname -a

Ran into this as well. The simplest fix is to rename the extended template to something else, like pcg_extended.
