New Revision: 1238

Log:
Use NULL instead of 0 consistently.

Since this is C and not C++, NULL is the stylistic choice
for pointer assignments and checking. This patch, kindly submitted
by Frederic Marchal <fmarchal AT perso DOT be> changes all of
places were ptl_mait is used in ifo_read.c. Thanks!
