[Bug c++/16818] New: Environment not set when using -static and global C++ ctors

["jurij dot rosenthal at web dot de" <gcc-bugzilla at gcc dot gnu dot org>]

The environment variable  extern char *environ is not set
on Solaris (SunOS 5.8 and 5.9) when using g++ -static.
(Works on Linux, though)

I checked this with different gcc version (2.95.1, 3.3.2, 3.3.4
and 3.4.1) on Solaris. 

Seems to me that this is caused by the run time system.

Executing:
bash-2.05$ ./test_getenv 
value of OSTYPE = (null)
value of OSTYPE = some


OSTYPE should say "some" in both cases.
