Description of problem:
To compile a program that uses the quotactl function is not possible as 
<linux/quota.h> and <sys/quota.h> must be included but have a conflicting 
struct: dqstats

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. make a file as such: myquotaprogram.cpp

#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <sys/quota.h>
#include <linux/quota.h>
// other headers as needed

int main(int argc, char* argv[], char *envp[])
{
   struct mem_dqblk info;
   long err = quotactl(QCMD(Q_GETQUOTA, USRQUOTA), "/dev/hda1", 500, (caddr_t)
&info);
}

2. try to compile this code and you get
gcc -c myquotaprogram.cpp -o theprogram.o
/usr/include/linux/quota.h:194: redefinition of `struct dqstats'
/usr/include/sys/quota.h:139: previous definition here
etc...

Actual Results:  /usr/include/linux/quota.h:194: redefinition of `struct 
dqstats'
/usr/include/sys/quota.h:139: previous definition here

Expected Results:  the program should compile

Additional info:

To stop this problem I commented out the dqstats struct in
/usr/include/sys/quota.h
as this is structure has one less member ( i.e. does not have the "version" 
member like <linux/quota.h> )

after this the program compiles and works as expected.
