[libungif]: configure script doesn't resolve CXXFLAGS

[Chris Delnooz]

Hi,

i'm trying to compile the graphics/libungif port version 4.1.0b1 on 
5.1-RELEASE, latests ports via cvsup. The configure script failes as 
follows:

Checking whether the C++ compiler (c++ FLAGS) works... no
configure: error: installation or configuration problem: C++ compiler 
cannot create executables

notice the FLAGS in that sentence... somehow the configure script 
doesn't resolve the CXXFLAGS or CPPFLAGS variable set in make.conf.
If i run configure by hand from work/libungif.../ it works just fine.. I 
couldn't figure out what was wrong with the configure script, so i hope 
you can find it...

i attached configure.log... for any questions, don't hesitate to contact 
me

regards
Chris Delnooz
