gmacros: fix unguarded use of __STDC_VERSION__

Browse Source 
According to the C spec, any undefined identifier used in a #if
expression is taken to have a numerical value of zero.

Commit db2367e878 introduced an #i
statement which depended on this behaviour.

gcc has a -Wundef option which warns about depending on this behaviour,
and unfortunately there are projects that are using -Werror=undef in
builds that include our headers.

Adding a check for defined(__STDC_VERSION__) before using the macro is
enough to silence gcc.
