* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025

* Crank WARNS.Juli Mallett2002-04-201-10/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Cast sizeof() to (int), as it's being compared against an int, not a size_t. If i is changed to a size_t, it means the logic must be slightly changed later in the flow, where --i is checked to be >= 0. I am not sure I want to make a logic change to account for clearing up a warning, when an aesthetic one will keep from modifying the logic. Other harmless casts, that I think I've made in the right directions. Make gpbc() an inline function, rather than an obfuscated macro, make its scratch space local, rather than global. The previous macro used a dirty hack (logical AND in place of a conditional) which would lead GCC to throw a fit (rightly so) as the logical check, as well as the incrementation of a variable, were not used for anything. const'ify a few places where gcc3 yells. xstrdup() some global consts in places where we xstrdup() when not using consts, but tried to assign them to non-consts before. Don't use execv(2) if we don't have the kind of arguments it wants. Reviewed by: asmodai obrien tjr Submitted by: tjr (a gcc3 build log) Notes: svn path=/head/; revision=95095
