Hello to the very few people that use FORTRAN.

Assuming you have gcc4 v4.3.3, remove CSWgcc4g95 and CSWgcc4g95rt and
install CSWgcc4gfortran and CSWgcc4gfortranrt.

gcc4g95 are from the previous gcc4 collection, either the name
shouldn't have changed or there should be some empty replacement
packages to remove the old files with special depends to install
the new packages are transparently.


$ pkginfo | grep CSWgcc4

application CSWgcc4corert        gcc4corert - GNU C Compiler Run Time

application CSWgcc4g++rt         gcc4g++rt - GNU C++ Compiler Run Time
application CSWgcc4gfortran      gcc4gfortran - GNU Fortran Compiler
application CSWgcc4gfortranrt    gcc4gfortranrt - GNU Fortran Compiler

Using the new packages I've just compiled a antique piece of code
- which has sections for Univacs and PDP-10s and used punch tapes
for "mass" storage - and I had I did have some other problems.

gcc3 and SunPRO both compiled fine.

Using /opt/csw/gcc4/bin/gcc as the compiler fails to link, trivial
example:

$ gcc main.f
Undefined                       first referenced
 symbol                             in file
main
/opt/csw/gcc4/lib/gcc/sparc-sun-solaris2.8/4.3.3/crt1.o
_gfortran_transfer_character        /tmp/ccUr3kjw.o
_gfortran_st_write                  /tmp/ccUr3kjw.o
_gfortran_set_options               /tmp/ccUr3kjw.o
_gfortran_st_write_done             /tmp/ccUr3kjw.o
ld: fatal: Symbol referencing errors. No output written to a.out


Use gfortran as the compiler.
export FC=/opt/csw/gcc4/bin/gfortran

$ gfortran main.f

but there is no RPATH to the FORTRAN lib:


$ ./a.out
ld.so.1: a.out: fatal: libgfortran.so.3: open failed: No such file or
directory
zsh: killed     ./a.out


$ LD_LIBRARY_PATH=/opt/csw/gcc4/lib ./a.out
 hello from the past

better workaround is to set -R/opt/csw/gcc4/lib on link but obviously
the package needs fixing properly.
