Make error in deparse.c

[ryanfmurphy]

Hello EnterpriseDB Team,

I am trying to build your (insanely useful sounding) mysql_fdw on Mac OS X. I get this error on make:

deparse.c:301:21: error: initializing 'Form_pg_attribute' (aka 'struct FormData_pg_attribute *') with an expression of incompatible type 'FormData_pg_attribute' (aka 'struct FormData_pg_attribute');

The full output is here:

I attempted to change the C code as it suggests by putting an & in front to take the address, but that just led to a slew of other errors, so I'll leave it to you guys. :)

Have you seen this before? I tried moving to an earlier commit (the latest release tag, REL-2_4_0, but still got the error.

Other details: Mac OS X Yosemite, building using a clang that says "Apple LLVM version 7.0.2 (clang-700.1.79)"

Thanks! Ryan
