fixed Peter build problems. I only doubled the number of entries, I don't know if this is the best fix.

Use of the klibccfg pathrewriter dll works only for main process: child forked processes can use only predefined libc rewriting rules (e.g. /@tmpdir).

This could be a dll init fault.

Sample testcase:

#include <sys/stat.h>

#include <stdio.h>
#include <unistd.h>

//#define DIR "/@tmpdir"
#define DIR "/$e/dati/yuri"

void test_dir( void)
{
   int ret;
   struct stat st;

   printf( "%d test dir\n", getpid());
   ret = stat( DIR, &st);
   if (ret != 0) {
	printf( "%d test dir failed\n", getpid());
	return;
   }
   printf( "%d test dir ok\n", getpid());
}


void test( void)
{
   FILE* f;

   printf( "%d test file\n", getpid());
   f = fopen( DIR "/fax.odt", "rb");
   if (f == NULL) {
	   printf( "%d test file failed\n", getpid());
	return;
   }
   fclose(f);
   printf( "%d test file OK\n", getpid());
}

void main( void)
{
   printf( "pid %d\n", getpid());

   fork();

   test();
   test_dir();

}

gid related functions are calling uid backend, here is the supposed corrected source code:
