robtillaart:
try

static prog_uint32_t TESTCONSTANT=4000000UL; // UL = unsigned long

does that help?

unfortunately not. Here is the test case and result

code:

#include <avr/pgmspace.h>

void setup() {

  Serial.begin(115200);  
  Serial.write("Here we go...\n");
  static prog_uint32_t TESTCONSTANT1=4000000L;
  static prog_uint32_t TESTCONSTANT2=4000000;
  static prog_uint32_t PROGMEM  MAX_U32=4294967200;

  Serial.write("TESTCONSTANT1=");
  Serial.println(pgm_read_dword_near(&TESTCONSTANT1));
  Serial.write("TESTCONSTANT2=");
  Serial.println(pgm_read_dword_near(&(TESTCONSTANT2)));
  Serial.write("MAX_U32=");
  Serial.println(pgm_read_dword_near(&MAX_U32));
}

void loop() {
}

result (notice the huge MAX_U32 is working for some reason)...

Here we go 
TESTCONSTANT1=29885333
TESTCONSTANT2=2484002864
MAX_U32=4294967200
