for internal includes, use `quote form` rather than `angle-bracket form`?

[greg-minshall]

from my application, i like to, e.g., #include <ctl/str.h>, with a -I pointing at some directory that includes ctl/ as a sub-directory.

but, includes to other ctl files within the ctl/ directory use "angle-bracket form", which does not look first in the directory containing the file (e.g., str.h) doing the #include.

i think if these angle-bracket form includes were changed to quote form, i.e., if

#include <vec.h>

were changed to

#include "vec.h"

all would be happy? (probably there's a downside, though?)

for background, a relevant section of the GNU cpp info pages says

By default, the preprocessor looks for header files included by the
quote form of the directive ‘#include "FILE"’ first relative to the
directory of the current file, and then in a preconfigured list of
standard system directories.  For example, if ‘/usr/include/sys/stat.h’
contains ‘#include "types.h"’, GCC looks for ‘types.h’ first in
‘/usr/include/sys’, then in its usual search path.

   For the angle-bracket form ‘#include <FILE>’, the preprocessor's
default behavior is to look only in the standard system directories.

cheers.

Seems fine to me
