cross-compiling involving 64-bit machines).
* Maintainers of `gcc' report that the back end definitely has
"broken" support for `COMPLEX' types. Based on their input, it
seems many of the problems affect only the more-general facilities
for gcc's `__complex__' type, such as `__complex__ int' (where the
real and imaginary parts are integers) that GNU Fortran does not
use.
Version 0.5.20 of `g77' works around this problem by not using the
back end's support for `COMPLEX'. The new option

the same "broken" mechanism as that used by versions of `g77'
prior to 0.5.20.
* `g77' currently inserts needless padding for things like `COMMON
