This accomplishes the same thing as a `find ... | sort` but with the
added benefit of clarity and avoiding a call to a subshell.
Additionally drop the -s option from call to patch as it is not POSIX.
The apply_patches script wasn't sorting the list of patches in
the "patches" directory before applying them. This left the list
in an indeterminate order. In most cases, the list is actually
sorted but rarely, they can be out of order and cause dependent
patches to fail to apply.
We now sort the list but the "sort" program wasn't in the
configure scripts so we needed to add that and regenerate
the scripts as well.
Resolves: #193
There are times when you need to troubleshoot issues with bundled
pjproject or add new features that need to be pushed upstream
but...
* The source directory created by extracting the pjproject tarball
is not scanned for code changes so you have to keep forcing
rebuilds.
* The source directory isn't a git repo so you can't easily create
patches, do git bisects, etc.
* Accidentally doing a make distclean will ruin your day by wiping
out the source directory, and your changes.
* etc.
This commit makes that easier.
See third-party/pjproject/README-hacking.md for the details.
