>Description:
Define a function "extern inline" compiling without
"-O1", "-O2" or with "-fno-inline" will result in
undefined references.
(This bug is triggered, if you compile a C file
 which uses <string.h> and strcpy and use
 "-O -fno-inline" as compiler flags)
>How-To-Repeat:
Compile with 
"gcc -o t t.c" or 
"gcc -O -fno-inline -o t t.c"
-------------t.c-------------------------------------
extern inline void t(int a)
{
  int b=a;
}
int main()
{
  t(3);
}
------------------------------------------------------
>Fix:
Compile with "gcc -O -o t t.c".
