Now it build fine !
I found a trick in a kind of RedHat bugzilla. But fully applied, it gave other 
errors, so I just kept what was needed... I'ld like to know it what I did 
could corrupt MapServer :
In both files mapstrinc.c and maphash.c, I added a line at the very begining, 
just after this one :
#include <ctype.h>

For mapstring.c, I added this line :
__const unsigned short int *__ctype_b;
and for maphash.c, this one :
__const __int32_t *__ctype_tolower;

Can this mess up MapServer ?

This is the trick (and warnings) from RedHat (not at all related to 
MapServer) :

Customer Fix
    -------------                 
    We used a brute force approach. Make the following code into
    a .c file, and include it in your program. At the start of 
    main(), call ctSetup().

    Make sure you compile statically or else the dynamic loader will 
    cause problems.

    I've seen others use macros, but this worked good enough for us... 

    #include <ctype.h>

    __const unsigned short int *__ctype_b;
    __const __int32_t *__ctype_tolower;
    __const __int32_t *__ctype_toupper;

    void ctSetup()
    {
    __ctype_b = *(__ctype_b_loc());
    __ctype_toupper = *(__ctype_toupper_loc());
    __ctype_tolower = *(__ctype_tolower_loc());
    }
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 

A / Will the dynamic loader (?) cause problem ?

B / They are talking about puting that in a start script. If MapServer don't 
run into troubles with this fix, would it be better to put it in a start 
script ? and then, where ?

Now I can't wait, I'm going to install Apache, a browser and custom the Itasca 
demo :p
