Fix potential double/float to int rounding errors
Not using lrint(f) when converting double/float to int
creates rounding errors.
This error was detected by TestParse::testParseDM4 failure
on Windows. It was creating rounding inconsistencies
on Linux too, see change in TestDiveDM4.xml.
Enable -Wfloat-conversion for gcc version greater than 4.9.0
