Another question! Do I have to add the line

#define _SCL_SECURE 0

to all my header and code sources even source of GMM++ or just on my own source files or even on file is enough?
What about those pragmas you mentioned?

try to define _SCL_SECURE=0 (warning ABI incompatible so all the code you link must use this flag)
for code using the stl heavily, it can result in 100x speedup.

perhaps also:

#pragma inline_recursion
#pragma inline_depth

and check all the optimisation are on.
