What I meant was that if the version fails, my guess is that most
plugin devs just bump the version in their plugin and recompile and
hope that the compiler catches any incompatible changes.  Only the
really conscientious ones will check which functions changed and if it
affects their code.

Urm, PLUGIN_VERSION_CHECK() generates a function that is a runtime
check doesn't it??

Don't you use:

#if GEANY_ABI_VERSION != xxx /* or whatever conditions */
#error ABI mismatch
#endif

for compile time check??
