DMDFE - where retStyle() is defined ?

[Carlos Smith]

Hi,

I am trying to bring DMDFE 0.173 to the 1.009 level.

The last thing missing to allow the production
of an exe is an undefined reference to a function 
retStyle().

That function is declared in mtype.h
within the struct TypeFunction, but
is not defined anywhere.

The declaration is also present in the version 0.173 but is
not used anywhere.

It is used by func.c in version 1.009.

Where is defined that function ?

I grepped every thing in the distribution and
i did not found it.
