Newbie linker errors - still missing _fltused _tls_index _tls_used localtime tzset mainCRTStartup

[malpropism]

Thanks for your suggestion.  In VS 2017, the Property Pages have 
a configuration drop down list box which allows you select among 
Active(Debug), Debug, Release, and All Configurations.  Mine was 
set to All Configurations, leaving me to believe that setting 
something would apply to both Debug and Release.   On the surface 
it seemed to work, setting one or another parameter was felt in 
both Debug and Release.  Verbose -v compilation, for example.

Your message gave me the idea to check the .vcxproj file directly 
and sure enough, Debug and Release were (quite) different, the 
relevant offending bit of XML in the Debug linker area was

<IgnoreAllDefaultLibraries>true</IgnoreAllDefaultLibraries>
