Just for the fun of it (actually in order to test some Fortran more
extensively),
I've compiled and installed g77, yesterday on our Solaris 2.5.1 machines.
After doing (in R's toplevel directory)
make distclean
./configure
now chooses g77 (instead of Sun's f77 which was chosen before).
I now do
make
make check
cd tests/Examples
and carefully compare base-Ex.Rout to an earlier version of base-Ex.Rout.
I've found the following problem
Rg77> 0^-1
[1] -Inf
instead of {+}Inf which was correctly returned before.
[[I also had that "make compare" after g77's installation
gave output of some differences, i.e., my g77 supposedly *does* have bugs.]]
--
Just to be sure:
Can some of you, particularly those for which
grep g77 config.cache
returns something, verify that
0^-1 == Inf
and those who get something else report this (either to me or to R-devel)?
Thanks in advance.

I get -Inf in Solaris 5.6 with g77.
