[Dev-C++] System specific?

[<v-...@ou...>]

Hello,

In university I am doing a programming course and last week we had an  
excercise using a given function to measure time:

----------------------------8< schnipp------------------------------
double MyTime() {
  struct timeval Tp;
  gettimeofday (&Tp, NULL);
  return Tp.tv_sec + (Tp.tv_usec /10000000.);
}
----------------------------schnapp >8------------------------------

At home I wanted to finish the program using Dev-C++ (current beta with  
fixed exe), but the compiler refused work when compiling this function  
with the message

----------------------------8< schnipp------------------------------
aggregate `struct timeval Tp' has incomplete type and cannot be  
initialized
----------------------------schnapp >8------------------------------

But in university (under Linux) it does work....so is this a problem of  
the compiler (gcc versions differ in university and at home) or a  
platform problem (Linux specific parts)? Sorry, I am no expert, just had  
two weeks of this course and I am only used to basic (under DOS).
