So, whose bug is it then ? glibc ?
cause before reduction, the code was
(http://bugs.gentoo.org/show_bug.cgi?id=365015):

#include <stdio.h>
static void w_i(void *fp, int (*outf)(void *, const char *, ...))
{
  outf(fp, ";%s\n", " - EOF -");
}

void write_cfg()
{
  FILE *fp = 0;
  w_i(fp, (int (*)(void *, const char *, ...))fprintf);
}

In gcc 4.5.3 it works likely due to internal fprint definition.
