When  I compile gsl-1.15 on by blfs box   I have lines like these in the 
/bin/sh ../libtool --tag=CC   --mode=compile gcc -DHAVE_CONFIG_H -I. -I.. -I..    
-O3 -fexceptions -m64 -fPIC -MT init2d.lo -MD -MP -MF 

I  want to know what the M switches i.e. -MT -MD -MP -MF   mean.  I have 
looked at the man pages of  libtool
( http://www.manpagez.com/man/1/libtool/)
and of the gcc,   and a few other places and found  no explanation for the -MT 
-MD -MP -MF.

Advice would be appreciated.
