[Trilinos-Users] How to define _MSC_VER

[David Cole]

This is almost certainly not a good idea.

Developers who write:
#ifdef _MSC_VER

expect that inside such an ifdef block, that they are compiling with cl, the
Microsoft compiler.

Sounds like there is more work to be done to get Trilinos to build on
Windows with MinGW gcc.

For now, it would be better if you could shift to using the Microsoft
compiler, as that is the one that is known to work with existing Trilinos
code. Even the free express edition should be just fine. (Better than
hacking flags like this to pretend that MinGW gcc is cl...)
