[galib] Compiling with gcc4

[Miguel Nicolau]

Hi Tim,

Edit the file ga/gaconfig.h (line 368) and change:

#if __GNUC__ == 3

to

#if __GNUC__ >= 3

You need this change in order to define the symbol 
"GALIB_USE_COMP_OPERATOR_TEMPLATES", which is used by GAAllele.h. Your 
change below is only useful to correct set the definition of 
"GALIB_LIBRARY_IDENTIFIER", inside gaversion.h.

Hope this helps

.Miguel
