Possible Bug In Gcc Prerelease While Build KDELibs

[Luke Mauldin <lukeskyfly at txk dot net>]

Hello, I have the latest CVS snapshot from today(5/25/01) and I have a 
problem while building KDELibs.  The error message is:

The exact lines of offending code are:

static inline long QRound (float inval)
{
  long ret;
  asm ("fistpl %0" : "=m" (ret) : "t" (inval) : "st");
  return ret;
}

This is in kdelibs-2.1.2 and I know they would not output something that 
would not build with gcc-2.95.3.  I also have the latest snapshot from the 
binutils CVS.  Is this really a GCC problem, or is this a KDE problem?  Can 
someone please help me?
