+Programmatically checking version
+***************

+Client code can programmatically check libgccjit version using:
+
+.. function:: int gcc_jit_version_major (void)
+
+ Return libgccjit major version. This is analogous to __GNUC__ in C code.
+
+.. function:: int gcc_jit_version_minor (void)

+ Return libgccjit minor version. This is analogous to

+ Return libgccjit patchlevel version. This is analogous to
