Revision 1.8, Sat Dec 14 02:34:38 2002 UTC (21 years, 5 months ago) by millert
Branch: MAIN
Changes since 1.7: +12 -34 lines
Instead of doing "if (c == EOF) return 0;" use the hook ('?') operator
instead to make these one-liners. Works around a compiler bug on vax
that affects both the libc and inline versions identically.
