Sort of. With your patch I get:
builtin/init-db.c: In function ‘copy_templates’:
builtin/init-db.c:127:3: warning: implicit declaration of function ‘system_path’ [-Wimplicit-function-declaration]
template_dir = to_free = system_path(DEFAULT_GIT_TEMPLATE_DIR);
^
builtin/init-db.c:127:26: warning: assignment makes pointer from integer without a cast
template_dir = to_free = system_path(DEFAULT_GIT_TEMPLATE_DIR);
Those are just warnings, and on some platforms the resulting code will
be fine, but it does violate the C standard to not have a valid
declaration in this case (it defaults to an int return type, which is
wrong; but simply as a matter of style we do not like implicit
declarations even when they are technically correct).
If you are going to be doing refactoring, I'd recommend building with
"-Werror" in your CFLAGS to catch such problems.
FWIW, the full set of CFLAGS I use (which I specify in config.mak) is:
CFLAGS += -Wall -Werror
CFLAGS += -Wno-format-zero-length
CFLAGS += -Wdeclaration-after-statement
CFLAGS += -Wpointer-arith
CFLAGS += -Wstrict-prototypes
CFLAGS += -Wold-style-declaration
-Peff
