So, it's using 'gcc' without any '-std=...' option.

By [1] it is probably a gcc version 4.8.x. By [2] it uses -std=gnu90 by default.
This explains the error messages at least.

So it boils down to what Paul hinted at: Why was the 'c99' module not
effective? For this, it would be good if you could attach config.log
(config.status and config.cache are not sufficient for analyzing this).
