I've already tried the nop thing and it doesn't work better.
I've quickly examined the generated assembly code, and there is no
obvious difference between the 2 programs, at least in the main part.
I'll try to watch deeper in the next few days.
Thanks for your answer again.

I compile my blink led program code (attached) for the msp430f5529
using mspgcc4 with option mmcu=msp430x5418.
The result is that the led is blinking too fast. I thought it was that
the delay was too

I believe some people are having some success using mspgcc4 and compiling
with the TI headers version of msp430-libc. There's a bug in the headers
right now

Show the code, please. Seems like you missed volatile keyword in delay cycle variable declaration
and more effective
Thanks for your quick reply !
Nothing changed with the volatile keyword.
Here is the code (sorry it was an attachment but it may not have passed) :
#include msp430f5529.h
int main ( void )
{
volatile unsigned long int i;
WDTCTL = WDTPW | WDTHOLD;
P1DIR = 1;

Try:
for(i=0;i5000;i++)
nop();

I believe some people are having some success using mspgcc4 and compiling
with the TI headers version of msp430-libc. There's a bug in the headers
right now that means you should include the legacy header msp430x552x.h
instead of the chip-specific one, and the compiler isn't aware of the 5529
