Demo:

$ type z*.c

DKA0:[arne]z1.c;1

#include "a/something.h"

DKA0:[arne]z2.c;1

#include "a/something.h"

DKA0:[arne]z3.c;1

#include "a/something.h"
$ type ab.com
$ loop:
$    fnm = f$search("z*.c")
$    if fnm .eqs. "" then goto endloop
$    define/user sys$input sys$command
$    edit/edt/comm=ab.edt 'fnm'
$    goto loop
$ endloop:
$ exit
$ type ab.edt
s\#include "a/\#include "b/\w
ex
$ @ab
...
$ type z*.c

DKA0:[arne]z1.c;2

#include "b/something.h"

DKA0:[arne]z2.c;2

#include "b/something.h"

DKA0:[arne]z3.c;2

#include "b/something.h"
$ type bc.com
$ loop:
$    fnm = f$search("z*.c")
$    if fnm .eqs. "" then goto endloop
$    define/user sys$input sys$command
$    edit/tpu/init=bc.eve 'fnm'
$    goto loop
$ endloop:
$ exit
$ type bc.eve
all replace "#include ""b/" "#include ""c/"
exit
$ @bc
...
$ type z*.c

DKA0:[arne]z1.c;3

#include "c/something.h"

DKA0:[arne]z2.c;3

#include "c/something.h"

DKA0:[arne]z3.c;3

#include "c/something.h"
$ type cd.com
$ loop:
$    fnm = f$search("z*.c")
$    if fnm .eqs. "" then goto endloop
$    define/user sys$input sys$command
$    edit/tpu/comm=cd.tpu 'fnm'
$    goto loop
$ endloop:
$ exit
$ type cd.tpu
eve_all_replace("#include ""c/", "#include ""d/");
eve_exit();
$ @cd
...
$ type z*.c

DKA0:[arne]z1.c;4

#include "d/something.h"

DKA0:[arne]z2.c;4

#include "d/something.h"

DKA0:[arne]z3.c;4

#include "d/something.h"

PS: Yes - both gawk and Perl can probably do it in way fewer lines.
