Won't compile under MINGW64 - drand48 is not partof stdlib

[spasmsagain]

Hi

Trying to compile this under Windows 10 on a MINGW64 (which is actually part of the windows Octave package)

Downloaded and built pcg_random.

Added in the headers and suggested on pcg_random help pages to use ldexp(pcg32_random(), -32) - 1.0; (not after cryptographic quality random numbers).

It builds but I'm getting
40 1.#INF00e+000 0.000000e+000
80 1.#INF00e+000 0.000000e+000
120 1.#INF00e+000 0.000000e+000
in the output_MMult0.m file which wont plot

Suggestions on fixing for Windows MINGW64?

Thanks
