RE: pspp rc4 on Mac: pfm-write errors

[Marshall DeBerry]

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.
