* exp_cg.adb (Homonym_Suffix_Length): Minor code reorganization.
2010-06-18 Thomas Quinot <quinot@adacore.com>
* sprint.ads: Minor reformatting.
* output.ads: Update obsolete comment.
2010-06-18 Ed Schonberg <schonberg@adacore.com>
* freeze.adb (Build_And_Analyze_Renamed_Body): if the renamed entity is
an external intrinsic operation (e.g. a GCC numeric function) indicate
that the renaming entity has the same characteristics, so a call to it
is properly expanded.
