The main goal of this patch is to get rid of a warning for the new Fortran
compiler:
(gdb) b 9
warning: Could not recognize version of Intel Compiler in: "Intel(R) Fortran 21.0-2087b"
Breakpoint 1 at 0x4048cf: file comp.f90, line 9.
While trying to fix this I analyzed DW_AT_producer of all latest Intel
compilers for C, C++ and Fortran. They do no longer necessarily start with
"Intel (R)" nor do they follow the internal and external version number
scheme that the original patch for this check assumed. Some newer compilers
even contradict the "intermediate" digit in the old version scheme and have
the MINOR number as the second digit, even when having 3 or 4 digits overall.
Therefore I rewrote the check to consider the first MAJOR.MINOR string found
as the version number. This might not be 100% correct for some older
internal compilers, but the only current user of this function is only
checking for the major version anyway. Hence this should be reliable enough
and extendable enough going forward.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
