I am attempting a build of the octave-2.1.73 package with the experimental gcc
3.4.4-2 compiler release.  Part of the octave configure script checks whether
linking from C to fortran libraries works; and this test is failing.  A partial
output is shown:
--snip
checking for Fortran libraries of g77...  -L/usr/lib/gcc/i686-pc-cygwin/3.4.4
-L/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../.. -lm -lfrtbegin -lg2c -lcygwin
-user32 -lkernel32 -ladvapi32 -lshell32
checking for dummy main to link with Fortran libraries... unknown
configure: error: linking to Fortran libraries from C fails
See `config.log' for more details.
--snip
config.log does not contain any error information I can see.

Any clues on what the issue might be would be appreciated.  I'm not sure
whether the configuration test is broken, or whether there is a real problem
with g77 on this compiler release.

Thanks,

Jim Phillips

PS octave on cygwin is currently compiled with gcc-3.3.3, due to a bug in
string handling in g++-3.4.4-1.  The new 3.4.4-2 release is designed to fix
that.
