 Compiler Limits
 ===============
 
    `g77', as with GNU tools in general, imposes few arbitrary
 restrictions on lengths of identifiers, number of continuation lines,
 number of external symbols in a program, and so on.
 
    For example, some other Fortran compiler have an option (such as
 `-NlX') to increase the limit on the number of continuation lines.
 Also, some Fortran compilation systems have an option (such as `-NxX')
 to increase the limit on the number of external symbols.
 
    `g77', `gcc', and GNU `ld' (the GNU linker) have no equivalent
 options, since they do not impose arbitrary limits in these areas.
 
    `g77' does currently limit the number of dimensions in an array to
 the same degree as do the Fortran standards--seven (7).  This
 restriction might be lifted in a future version.
