Revision 1.17, Thu Jan 18 17:49:51 2007 UTC (17 years, 4 months ago) by espie
Branch: MAIN
CVS Tags: OPENBSD_4_2_BASE, OPENBSD_4_2, OPENBSD_4_1_BASE, OPENBSD_4_1 Changes since 1.16: +9 -5 lines
* add an extra argument to the dir lookup functions to say whether we
should look in the current directory.
* refactor include files treatment to have a separate function to look
for an include.
* use both pieces to make sure system includes do not get looked up
in the current directory unless everything else fails.
This is != from the netbsd solution to the same problem, which stuffs
`magic' entries into filepaths to say whether dot should be looked at
first or last.
feature requested by matthieu@.
