Rerunning the code snippet with the semicolon corrected produces the same
set of warning messages; running the program with (long double) 30 produces
a pretty standard warning regarding printf ("incompatible implicit
declaration of built-in function 'printf'") and no other warnings.
Explicit casting to allocate sufficient space is needed, perhaps?

Sorry. The semicolon should have been outside the braces, like this:
#include <stdio.h>
int
main(int argc, char **argv)
{
static const double foo[1] =
{
30 * 30 * 30 * 30 * 30 * 30 * 30 *
30 * 30 * 30 * 30 * 30 * 30 * 30 *
30 * 30 * 30 * 30 * 30 * 30 * 30
};
printf("%g\n",foo[0]);
}
I'm going to file a bug report on the GCC compiler with Apple, and use
the
pfm_write.c module as the example.
The Apple people are much more likely to act on a bug report if you can give
them a very concise test case. If the above works, then try replacing
30 with (long double) 30 and see what happens.
