[pgrouting-users] importance of -frounding-math compilation flag?

[William Kyngesburye]

I'm recompiling pgrouting on OS X Lion, using the clang compiler.  clang does not have the -frounding-math option.

I found one reference that the clang equivalent is --disable-fpmath, but that just causes and error "unsupported option '--disable-fpmath'".  I could find no documentation that clang has or had this option, or something similar.

Is the rounding behavior critical?
