 Not on DragonFly.
 
 Looks like bug on NetBSD, as it pulls in ../../mk/compiler/f2c.mk
 
 On NetBSD:
 tx:m17n-db$ make show-var VARNAME=_GCC_USE_F2C                
 yes
 
 And on DragonFly:
 
 pkgbox:/home/reed/pkgsrc/misc/m17n-db> bmake show-var VARNAME=_GCC_USE_F2C
 no
 
 
 Why does gcc.mk do the following?
 
 # On older NetBSD systems and where the Fortran compiler doesn't exist,
 # force the use of f2c-f77.
 #
 _GCC_USE_F2C=   no
 .if !exists(${FCPATH})
 _GCC_USE_F2C=   yes
 .else
 .  for _pattern_ in 0.* 1.[0-4] 1.[0-4].*
 .    if !empty(MACHINE_PLATFORM:MNetBSD-${_pattern_}-*)
 _GCC_USE_F2C=   yes
 .    endif
 .  endfor
 .endif
 .if !empty(_GCC_USE_F2C:M[yY][eE][sS])
 .  include "../../mk/compiler/f2c.mk"
 .endif
 
 Maybe the above should probably only happen if 
 !empty(USE_LANGUAGES:Mfortran)
