Yes I did read the comments and the patch I made specifically checks the compiled output to make
sure it matches what's expected: https://github.com/php/php-src/commit/648673bffe7a7c63ce6223fcbac7c118a114c893

On Mac OS X 10.9 with gcc 4.2.1 from XCode I've had no issues compiling. And same with a
gcc-4.9 from homebrew. I don't have access to OS X 10.6.

Can you pastebin or gist your config.log file with the failure? 

Also can you compile and run this snippet and paste the output?
#include <stdio.h>
#include <string.h>
int main(int argc, char **argv) {
  typedef float dec32 __attribute__((mode(SD)));
  dec32 k = 99.49f;
  double d2 = (double)k;
  const char *check_str = "99.49";
  char print_str[32];
  snprintf(print_str, 32, "%f", d2);
  printf("Expected: %s, Actual: %s\n", check_str, print_str);
  return memcmp(print_str, check_str, 5);
}

Thanks for making these snapshots available on a different server since snaps.php.net and qa.php.net
are still down.

I tested 5.5.19RC1 and 5.6.3RC1, and there is no change in the issue.

Did you read all my previous messages in which I explained what the problem and solution are?

I'd like to try the snapshot, but snaps.php.net has been down for days.

"This service is unavailable at the moment. Please try again in a day"

Ah I just repeated a bunch of what you said :) Should've read the full email thread before
replying. 

I am marking the bug again as "Try a snapshot".
