[GRASS-dev] compiling grass_trunk under MSYS

Hi,

when I try to compile GRASS code from trunk under MSYS I get

spawn.c: In function `G_spawn':
spawn.c:81: warning: passing arg 3 of `_spawnv' from incompatible pointer type
spawn.c: In function `do_bindings':
spawn.c:218: warning: `return' with a value, in function returning void
spawn.c: In function `do_spawn':
spawn.c:227: error: void value not ignored as it ought to be
spawn.c:229: warning: passing arg 3 of `spawnvpe' from incompatible pointer type
spawn.c:229: warning: passing arg 4 of `spawnvpe' from incompatible pointer type
make: *** [OBJ.i686-pc-mingw32/spawn.o] Error 1

changing prototype of do_bindings from

static void do_bindings(char **env, struct binding *bindings, int num_bindings)

to

static char** do_bindings(char **env, struct binding *bindings, int
num_bindings)

solves compilation. But I am not sure how to fix it in better way.

Oops. This was the last thing I did before my Linux box died and I
became incommunicado.

static void do_bindings(char **env, struct binding *bindings, int num_bindings)

That's the correct fix.
