Fixing cygdrop.
$ net helpmsg 122 The data area passed to a system call is too small.
A quick look into the sources shows that the maximum buffer size for the group list returned by GetTokenInformation is wrongly computed:
max_groups = 100; char groups_buf[sizeof(DWORD) + max_groups * sizeof(SID_AND_ATTRIBUTES)];
The SID_AND_ATTRIBUTES structure only contains a pointer to the SID, so what's missing is actual space for the SIDs.
But it would be better to leave that to the OS anyway:
