Comment (by calum.mitchell@…):

 I ran into this problem when reading the documentation for 1.45.0 and
 trying to compile/run the example code.

 The resolution appears to be:

 desc.add_options()
     ("help", "produce help message")\\
     ("compression", value<string>(), "compression level")\\
     ("verbose", value<string>()->implicit_value("0"), "verbosity level")\\
     ("email", value<vector<string>>()->multitoken(), "email to send to")\\
     ;

 As mentioned in an earlier comment, the use of value<vector<string>>() for
 a multitoken() option means that the option can occur more than one time
 on the command line.
