GP Makefile compiling twice

[Michael Somos <somos@grail.cba.csuohio.edu>]

Pari Developers,

I am using the latest CVS and following the recommended instructions
for making the gp software. However, I notice that it seems to be
compiling the source twice. In summary, I do './Configure' ,'make gp',
and 'make install'.

Here is an edited version of the script :

danube:/tmp/local/pari> ./Configure --prefix=/u/home/somos/u/pari
Configuring pari-2.2.3 (DEVELOPMENT VERSION)

Shall we try to build pari 2.2.3 (development) now (y/n)? [n]
Ok. Type "make install" when you are ready
Bye !

Notice that all modules from 'mp.c' on seem to be compiled twice.
Any idea if this is a feature? Shalom, Michael
