There's a comment here seen at the top of this hunk that says

// Check for the special symbol '+INF', which means +Infinity.  Note: C99
// requires strtof to parse '+INF' as +Infinity, but we still support some
// non-C99-compliant compilers (e.g. MSVC).

could an MSVC user test if strof properly parses +INF with the
required versions of MSVC?
