[Python-checkins] CVS: python/dist/src/Objects floatobject.c,2.71,2.72

[Tim Peters]

Update of /cvsroot/python/python/dist/src/Objects
In directory slayer.i.sourceforge.net:/tmp/cvs-serv28925/python/dist/src/objects

Modified Files:
	floatobject.c 
Log Message:
Replace SIGFPE paranoia around strtod and atof.  I don't believe these
fncs are allowed to raise SIGFPE (see the C std), but OK by me if
people using --with-fpectl want to pay for checking anyway.
