When compiled as an "extra" compiler,  gcc  will  go  search  for  its
include files in /usr/local/include. Since gcc is the native  compiler
in  FreeBSD,  it  only  goes  looking  in  the  standard  /usr/include
directory.

Easiest choice: tell your users to aways add a -I/usr/local/include in
the cc command line option in their makefiles

Alternatively,  you  can  rebuild  gcc  from  the GNU sources with the
default setup of searching /usr/local/include (that's what "configure"
chooses  by default). Note that this compiler should *not* be used for
system tasks as kernel generations. Use /usr/bin/cc.

What I did on my system is removing /usr/bin/gcc (which is a hard link
to  /usr/bin/cc)  so that "cc" invokes the standard compiler and "gcc"
the  one  I  have  built  from   GNU   sources   (which   resides   in
/usr/local/{bin, include, lib, ...})

Good luck,

_A_
