gnat_ugn.texi: Document -gnatDnn/-gnatGnn
2009-04-07 Robert Dewar <dewar@adacore.com>
* gnat_ugn.texi: Document -gnatDnn/-gnatGnn
* opt.ads (Sprint_Line_Limit): New parameter
* sprint.adb: Usa Sprint_Line_Limit instead of Line_Limit throughout
* switch-c.adb: Recognize -gnatDnnn and -gnatGnnn switches
* usage.adb: Output information for -gnatGnn -gnatDnn
* make.adb: Minor reformatting
* mlib-tgt-specific-vms-alpha.adb: Minor reformatting
* mlib-tgt-specific-vms-ia64.adb: Minor reformatting
