Ease building with custom includedir.
fix inline documentation for SparseMatrixCSC
fix mpfr test failure on 64 bit Windows

Ref https://github.com/JuliaLang/julia/issues/3399

BigFloat^Int goes to MPFR on every platform other than Win64,
because Win64 is the only place that Julia Int is bigger than Clong.
On Win64 it's going to power_by_squaring resulting in a differently-rounded result.

Cartesian: parse-time evaluation of A[3] when A is known

This allows efficient operations like this:

    indexes = [:i_2, :i_3]
    macroexpand(:(@nexprs 2 d->$indexes[d]))

This also centralizes the parse-time evaluation of expressions,
combining the new array reference with the previous arithmetic
and conditional evaluation, so that it can be done on a single
pass through the expression tree.

This is not really punctuation, just an operator. It's also not just
for function chaining, it's also used for redirection. It's also not
clear what function chaining means. Also, people shouldn't use it.
