Description:
isfinite() used in /sql/field.cc and /sql/item_func.h is not available on QNX 6.2.1.

This bug was introduced in 5.1, since 5.0 works around this with HAVE_FINITE preprocessor define.

How to repeat:
configure, make on QNX 6.2.1

Suggested fix:
test for presence of isfinite() should be included in the .configure script. On QNX 6.2.1, the function that does the same is actually finite() - replacing it in the source code worked and it built fine.

QNX is not a supported platform anymore.
