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.
