[R-SIG-Win] Rtools45 returning many -Wimplicit-function-declaration errors

[Avraham Adler]

That's weird. Restarting the compilation allowed Matrix to finish and
it passes make check-devel/check-recommended. I am so confused.

So, for the time being, passing "-Wno-implicit-function-declaration"
in line 8 of src/extra/blas/Makevars.win when compiling blas00.c
solves this problem. Is there any reason to dig further?

Thank you again,

Avi
