Revision 1.45, Sat Feb 16 21:27:50 2002 UTC (22 years, 3 months ago) by millert
Branch: MAIN
CVS Tags: OPENBSD_3_1_BASE, OPENBSD_3_1
Changes since 1.44: +11 -11 lines
Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.
