ggc-simple.c not K&R C

[Jim Wilson]

I tried a SunOS4 build using the Sun C compiler.  I got an error while
compiling ggc-simple.c because it uses "long double", which this old K&R C
compiler does not support.  I just fixed this by changing it to "double", but
you probably want a better solution.  Maybe check __STDC__?
