Woe with doSetUnset

[john o goyo]

Gaius:

I will not be setting up my Sparc box for another few weeks, so I am 
concentrating on mc.  To obtain the required header files, I am building 
a cross-compiler on my M1 Mini for aarch64-unknown-freebsd10.1 and 
encountering a strange error.

/usr/bin/g++ -std=gnu++11 -DHAVE_CONFIG_H -g -c -I. -Im2/gm2-libs 
-I../../../src/gcc-git-devel-modula2/gcc/../include 
-I../../../src/gcc-git-devel-modula2/gcc -I. -Im2/mc-boot-ch

clang: warning: treating 'c' input as 'c++' when in C++ mode, this 
behavior is deprecated [-Wdeprecated]

error: no matching function for call to 'doSetUnset'
      return doSetUnset (&t->c_iflag, IGNBRK, b);

But doSetUnset is defined at ll. 394+ in the same file Gtermios.c.

I am somewhat stumped by this one.
