with -E:

static void __attribute__(())
x_error_quitter (display, error)
     Display *display;
     XErrorEvent *error;
{
  char buf[256], buf1[356];





strace -f -s 2000000 -- i686-pc-linux-gnu-gcc -E -D_BSD_SOURCE   -Demacs

grep noinline|less


shows that /usr/include/linux/compiler.h is the problem:

   154  #ifndef noinline
   155  #define noinline
   156  #endif

I guess I could try contacting the lkml? But maybe for now it would be
better to put an #undef in xterm.c or something.
