Remarks about the building process

[Jean-Charles Malahieude]

Some nitpicks during the building process, on a fresh repository:


1- the configure script:
For a long time now, I always get this:

configure: WARNING: autoconf <= 2.59 with g++ >= 3.3 gettext test broken.
configure: WARNING: Trying gcc, cross fingers.

It does not break anything;  it is just boring since:

# autoconf --version
autoconf (GNU Autoconf) 2.61

# g++ --version
g++ (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8)


I consider this kind of thing might even become "dangerous":
as we say in French: " A force de crier au loup..." (after having yelled 
so often at the wolf...)


2- The make stage:

I don't report  this kind of warnings:
 conversion to 'xx' from 'yy' may alter its value
or
 part-combine-iterator.cc:22: warning: 'typedef' was ignored in this 
declaration


but those ones just bother me, since I am unable to analyze what is 
going on:

key-engraver.cc:83: warning: suggest parentheses around && within ||

note-collision.cc: In function 'void check_meshing_chords(Grob*,

I truly hope someone understands my questioning.
