[Bug preprocessor/45038] New: __DBL_MIN__ result in old-style-cast

[buaa_figo at 126 dot com]

My code use DBL_MIN with warning option "-Wold-style-cast -Werror". 
But I found DBL_MIN definition has changed in gcc4.5.0
When use "./cpp -dM /dev/null", I got :
#define __DBL_MIN__ ((double)2.22507385850720138309e-308L)

Why gcc use old style cast in macro?
