commit 73e9e18ea09ffffcaac50237def0d9728a213c02
Author: Scott Talbert <swt@techie.net>

    Fix STC compilation with GCC6
    
    Use std::abs() from <cmath> instead of abs() from <math.h> to avoid problems
    with ambiguous overloads.
    
    Closes #17147.
    
    Closes https://github.com/wxWidgets/wxWidgets/pull/222
