22/* This file currently is just a stub through which g77's copy
23   of netlib's libf2c, which g77 builds and installs as libg2c.a
24   (to avoid conflict), #include's g77's version of f2c.h, named
25   g2c.h.  That file is, in turn, produced via g77's library
26   configuration process from g2c.h.in.
27
28   By going through this extra "hoop", it is easy to provide for
29   libg2c-specific configuration and typedefs that aren't appropriate
30   in g2c.h itself (since that is intended to be installed so it can
31   be shared with f2c users), without changing the libf2c (libg2c)
32   routines themselves.  (They continue to #include "f2c.h", just
33   like they do in netlib's version.)  */

37/* For GNU Fortran (g77), we always enable the following behaviors for
38   libf2c, to make things easy on the programmer.  The alternate
39   behaviors have their uses, and g77 might provide them as compiler,
40   rather than library, options, so only a single copy of a shared libf2c
41   need be built for a system.  */

43/* This makes unformatted I/O more consistent in relation to other
44   systems.  It is not required by the F77 standard.  */

48/* This makes ERR= and IOSTAT= returns work properly in disk-full
49   situations, making things work more as expected.  It slows things
50   down, so g77 will probably someday choose the original implementation
51   on a case-by-case basis when it can be shown to not be necessary
52   (e.g. no ERR= or IOSTAT=) or when it is given the appropriate
53   compile-time option or, perhaps, source-code directive.

59/* Most Fortran implementations do this, so to make it easier
60   to compare the output of g77-compiled programs to those compiled
61   by most other compilers, tell libf2c to put leading zeros in
62   appropriate places on output.  */
