Ive ripped it from a project I am porting to MSVC. when I build the above program
in debug mode I get;
624 ms Link
1 calls<br/>
2520 ms CL
1 calls<br/>
<br/>
Build succeeded.<br/>
<br/>
Time Elapsed 00:00:03.42
all is well, but when in release mode
761 ms CL
1 calls<br/>
219836 ms Link
1 calls<br/>
<br/>
Build succeeded.<br/>
<br/>
Time Elapsed 00:03:40.69

same program with g++
$ time g++ deneme.cc -O2 -o dengg<br/>
<br/>
real 0m3.396s<br/>
user 0m0.000s<br/>
sys 0m0.015s
the link time increases exponentially with the number of
entries in denemedata.h. if I remove the constructor in mon_resist_def (also putting the MR_VUL_POISON in a initializer list of course)
then it links it in half time ,but still very long.
Any ideas why that might be?

Edit : using MSVC10
