2008-05-29 Arnaud Charlet <charlet@adacore.com> PR ada/864 * osint.ads, osint.adb (Program_Name): New parameter "Prog" to allow recognition of program suffix in addition to prefix. * gnatchop.adb (Locate_Executable): Add support for prefix. * make.adb, gnatcmd.adb, gnatlink.adb, prj-makr.adb, mlib-utl.adb: Adjust calls to Program_Name.
