// GitHub Issue #937: "Support for HP-UX" (version 11.11, Dec. 2000)
//
// C90 does not provide roundf() but nanosvg.h uses it although
// nanosvgrast.h has a replacement function: nsvg__roundf()
//
// Solution: use nsvg_roundf() instead.
// Advantage: we don't need to check system macros.
//
// Note: using nsvg__roundf() in nanosvg.h should be applied upstream.
// Once this is available we can remove this comment block and
// the following 3-line "fix":
#include <math.h> // must be before #define below !
static float nsvg__roundf(float x); // prototype (see nanosvgrast.h)
#define roundf nsvg__roundf // redefinition (#937)
// End of GitHub Issue #937. Remove this entire block when upstream is patched.
