Subject: make the definition of _Complex_I explicitly complex
X-Git-Tag: v1.1.6~22
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=a9c2294eef0b4d7e7bcf6155ecb46b25703a80eb;p=oweals%2Fmusl.git

make the definition of _Complex_I explicitly complex

it's unclear whether compilers which provide pure imaginary types
might produce a pure imaginary expression for 1.0fi. using 0.0f+1.0fi
ensures that the result is explicitly complex and makes this obvious
to human readers too.
