This depends on the makefile and configure fragments in ../f. - -Some small changes have been made to the f2c distributions of lib[FI]77 which -come from <ftp:bell-labs.com/netlib/f2c/> and are maintained (excellently) by -David M. Gay <dmg@bell-labs.com>. See the Notice files for copyright -information. I'll try to get the changes rolled into the f2c distribution. - -Files that come directly from netlib are either maintained in the -gcc/f/runtime/ directory under their original names or, if they -are not pertinent for g77's version of libf2c, under their original -names with `.netlib' appended. For example, gcc/f/runtime/permissions.netlib -is a copy of f2c's top-level`permissions' file in the netlib distribution. -In this case, it applies only to the relevant portions of the libF77/ and -libI77/ directories; it does not apply to the libU77/ directory, which is -distributed under different licensing arrangements. Similarly, -the `makefile.netlib' files in libF77/ and libI77/ are copies of -the respective `makefile' files in the netlib distribution, but -are not used when building g77's version of libf2c. - -The `README.netlib' files in libF77/ and libI77/ thus might be -interesting, but should not be taken as guidelines for how to -configure and build libf2c in g77's distribution. - -The packaging for auto-configuration was done by Dave Love <d.love@dl.ac.uk>. -Minor changes have been made by James Craig Burley <burley@gnu.ai.mit.edu>, -who probably broke things Dave had working. :-) - -Among the user-visible changes (choices) g77 makes in its -version of libf2c: - -- f2c.h configured to default to padding unformatted direct reads - (#define Pad_UDread), because that's the behavior most users - expect. - -- f2c.h configured to default to outputting leading zeros before - decimal points in formatted and list-directed output, to be compatible - with many other compilers (#define WANT_LEAD_0). Either way is - standard-conforming, however, and you should try to avoid writing - code that assumes one format or another. - -- dtime_() and etime_() are from Dave Love's libU77, not from - netlib's libF77. |
