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.
