No functionality modified.
Tested on x86_64-pc-linux-gnu, committed on trunk
2012-02-08 Vincent Celier <cel...@adacore.com>
* gcc-interface/Make-lang.in: Add g-byorma.o to gnatbind objects
(g-buorma is now imported by sinput).
Update dependencies.
* scn.adb (Initialize_Scanner): Call Check_For_BOM
* sinput-p.adb (Source_File_Is_Subunit): Call Check_For_BOM
* sinput.adb: New procedure Check_For_BOM
* sinput.ads: New procedure Check_For_BOM
