[xmlsec] link error building xmlsec 1.0.2

[Matthias Jung]

Hi Aleksey,

changes in the xmlsec 1.0.2 release in src/openssl/x509.c cause a link 
error on Solaris OS
(I have tested Solaris 7 and 9 using gcc 2.95.3). On Linux this error 
does not occur.

Please have a look at the compile output I got:

gcc -g -O2 -DXMLSEC_NO_XSLT=1 -DXMLSEC_NO_XKMS=1 -o .libs/xmlsec1 
xmlsec.o crypto.o cmdline.o  ../src/openssl/.libs/libxmlsec1-openssl.so

../src/openssl/.libs/libxmlsec1-openssl.so
unsetenv                            
../src/openssl/.libs/libxmlsec1-openssl.so
ld: fatal: Symbol referencing errors. No output written to .libs/xmlsec1
collect2: ld returned 1 exit status

I have checked Solaris documentation for this functions and it seems 
like 'setenv' and 'unsetenv' are not existant on Solaris OS.
Does anybody else using Solaris have this problem?
Do you have a clue of how to solve this problem?

Thanks
