Linux RedHat 5 Enterprise - R2013a - LoadLibrary Error

Anyone have any insight on how to troubleshoot this error? This is the only command in thunk.m: loadlibrary('librefprop','header.h','mfilename','rp_proto64')

>> thunk

header.h:

Here are the first few lines of header.h:

void __cdecl setupdll_ ( long *, char [ 10000 ], char [ 255 ], char [ 3 ], long *, char [ 255 ], long , long , long , long );
void __cdecl setrefdll_ ( char [ 3 ], long *, double *, double *, double *, double *, double *, long *, char [ 255 ], long , long );
void __cdecl setmixdll_ ( char [ 255 ], char [ 255 ], char [ 3 ], long *, char [ 10000 ], double *, long *, char [ 255 ], long , long , long , long , long );
void __cdecl setmoddll_ ( long *, char [ 3 ], char [ 3 ], char [ 60 ], long *, char [ 255 ], long , long , long , long );
void __cdecl setpathdll_ ( char [ 255 ], long );

The correction was to remove the __cdecl stack command all together. It turns out that linux gcc normally adds this in automatically for 64 bit systems making it redundant. (the best I could understand)
