/* This file currently is just a stub through which g77's copy
|
|
of netlib's libf2c, which g77 builds and installs as libg2c.a
|
|
(to avoid conflict), #include's g77's version of f2c.h, named
|
|
g2c.h. That file is, in turn, produced via g77's library
|
|
configuration process from g2c.h.in.
|
|
|
|
By going through this extra "hoop", it is easy to provide for
|
|
libg2c-specific configuration and typedefs that aren't appropriate
|
|
in g2c.h itself (since that is intended to be installed so it can
|
|
be shared with f2c users), without changing the libf2c (libg2c)
|
|
routines themselves. (They continue to #include "f2c.h", just
|
|
like they do in netlib's version.) */

/* For GNU Fortran (g77), we always enable the following behaviors for

libf2c, to make things easy on the programmer. The alternate
|
|
behaviors have their uses, and g77 might provide them as compiler,
|
|
rather than library, options, so only a single copy of a shared libf2c
|
|
need be built for a system. */

/* This makes ERR= and IOSTAT= returns work properly in disk-full

situations, making things work more as expected. It slows things
|
|
down, so g77 will probably someday choose the original implementation
|
|
on a case-by-case basis when it can be shown to not be necessary
|
|
(e.g. no ERR= or IOSTAT=) or when it is given the appropriate
|
|
compile-time option or, perhaps, source-code directive.

by most other compilers, tell libf2c to put leading zeros in

appropriate places on output. */
