X-Git-Tag: v2.6.23-rc1~257^2~8
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c05190371d5ca360b75864cfcf930e8bf3addeb1;p=linux-2.6

kbuild: use POSIX BRE in headers install target

The sed expression used at the moment in scripts/Makefile.headersinst
relies on the (handy) GNU extension where you can escape ERE's in an
otherwise BRE without using the GNU -r option.  The following patch
replaces this "\+" usage with a functionally equivalent POSIX BRE compliant
"\{1,\}".  Tested with `make headers_install` against blackfin/x86_64/i386
targets.

Stupid whiny OS X users and their crappy sed ;)
