--- Comment #18 from Nicolas Boulenguez <nicolas at debian dot org> --- Created attachment 57897 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57897&action=edit rewrite commit 3/8 so that Duration'Size may be 32 Would version 4 of commit 3/8 be OK? It only modifies s-crtl.ad[bs]. A bit out of the subject, but if GNAT supports Duration'Size = 32, a-reatim.adb s-ransee.adb a-calend.adb probably deserve comments about the way the conversion deals with the size difference and sign bit.
