A few notes regarding cygfakesu.c:

uid_t root_uid = 18;
gid_t root_gid = 544;

uid_t my_uid = -1;
gid_t my_gid = -1;

struct passwd my_pw;
struct group my_grp;

char str255[255];
...
uid_t uid_get(uid_t uid){
...
gid_t gid_get(gid_t gid){
...
etc...

Variables and functions not exported by the fakesu.h file should be declared as static. Note that the cygfakesu.def file has no effect when generating a static lib.


$ gcc -Wall cygfakesu.c
...
cygfakesu.c:52:2: warning: implicit declaration of function âgetuidâ [-Wimplicit-function-declaration]
...

Include of unistd.h is missing.


int su_setgroups(int size, const gid_t *list){
...
    gid_t l[s];
...
    return setgroups(size, &l);

setgroups() 2nd parameter expects a type compatible to 'pointer to const git_t'
The type of '&l' is 'pointer to array of git_t' :-)
(cosmetic in C, compilation would fail in C++):
