Make macros to prevent double-inclusion in headers consistent. Signed-off-by: Junio C Hamano <junkio@cox.net> 2007-04-29 08:38:52 +02:00			`#ifndef GIT_EXEC_CMD_H`

Exec git programs without using PATH. The git suite may not be in PATH (and thus programs such as git-send-pack could not exec git-rev-list). Thus there is a need for logic that will locate these programs. Modifying PATH is not desirable as it result in behavior differing from the user's intentions, as we may end up prepending "/usr/bin" to PATH. - git C programs will use exec_git_cmd() APIs to exec sub-commands. - exec_git_cmd() will execute a git program by searching for it in the following directories: 1. --exec-path (as used by "git") 2. The GIT_EXEC_PATH environment variable. 3. $(gitexecdir) as set in Makefile (default value $(bindir)). - git wrapper will modify PATH as before to enable shell scripts to invoke "git-foo" commands. Ideally, shell scripts should use the git wrapper to become independent of PATH, and then modifying PATH will not be necessary.

Const tightening. Mark Wooding noticed there was a type mismatch warning in git.c; this patch does things slightly differently (mostly tightening const) and was what I was holding onto, waiting for the setup-revisions change to be merged into the master branch.
