Actually, I don't want float.h as an implied include in this case since 
we are defining an internal-use
variable as opposed to something we need to expose to the end-user (in 
which case we would check for
gcc and avoid the include if possible).

So, I have undergone moving the macro to libc/stdlib/local.h and adding 
libm/common/local.h where it can
safely include float.h without affecting the end-user.  All the files 
needing _LDBL_EQ_DBL now include the "local.h" file in its directory.  
The patch will be checked in shortly.
