[PD] obj3 crashes when compiled with MinGW on XP

[s.koepf]

Hello,

while compiling the externals examples (given in v.0.39.2) with 
different compilers on XP I found:

when compiled with MinGW pd crashes immediately when a number is given 
to the left inlet of [obj3]. The same happens with example obj4.c (the 
other examples work fine). Compiled for example with lcc-win32 no 
problem occurs.

This error seems to depend on the function outlet_float().

Any idea?
