Are you sure about this ?

AFAIK, they  have opposite order of arguments in stack. In cdecl caller
will clean up stack after the call (raise ESP) while in stdcall this is
job of called function. I see no reason to change this because of
32\64\128 bit architecture of CPU.

Anyway, the calling convention for a Firebird UDF is still cdecl either
for x86_64 or x86_32.

PS: Don't forget to use ib_util_malloc() from ib_util.dll to allocate
memory for the UDF result string declared as FREE_IT.
