Revision 1.64, Sun Nov 4 23:25:59 2012 UTC (7 years, 1 month ago) by christos
Branch: MAIN
CVS Tags: yamt-pagecache-base8, yamt-pagecache-base7, agc-symver-base, agc-symver
Changes since 1.63: +17 -12 lines

Over the years this header gained a lot of disparate functionality
and willy nilly people kept adding headers appropriate to the new
functionality  So we reached where we are today, this header causes
lots of namespace conflicts (for example you cannot use util.h from
a lex file, because ECHO is macro used in lex, and ECHO is defined
to 8 in termios). Roll back time, and remove all the unnecessary
includes, leaving it to the program to include the ancillary headers
they need.
