Thanks for your script, which is indeed handy.  I attach a slighly 
improved version, which also "cleans" the autogen and configure steps, and 
which displays error/warning messages in bold red.  I also replaced your 
"nproc" by "expr $(nproc) / 2 + 1", IME using nproc makes the computer 
unuseable, and is not much faster than nproc/2+1.
