[PATCH] Fix __STDC_VERSION__ tests.

[Matthieu Herrb]

the existing test:
defined(__STDC__) && (__STDC_VERSION__ - 0 >= 199901L) causes an
warning when building X stuff with gcc -Wundef. Other tests for
 __STDC_VERSION__ in the X sources all use
defined(__STDC_VERSION__) && (__STDC_VERSION__ -0 >= 199901L)
