error: cannot compute sizeof (short)

[RooZ]

I'm trying to compile a program which requires MySQL to work properly, except I keep getting the error:

checking size of short... configure: error: cannot compute sizeof (short), 77

The log says:

configure:20803: checking size of short

I haven't the slightest idea how to fix it
