Selects a shorter format for some warning messages. At present, the only warnings controlled by this flag are those that are printed at the end of processing each subprogram. These include warnings about variables that are set but not used or used before set, variable names that do not conform to the Fortran 77 standard, etc. (These warnings may be suppressed entirely depending on other flags, such as the -usage or -f77 flags.) In the default format each variable is listed on a separate line, along with the line number where the variable is declared, set or used, according to the nature of the warning. The briefer format simply lists all variables to which the warning applies, with up to 4 variables per line.
