I'm trying to build a small code that works across multiple platforms and compilers. I use assertions, most of which can be turned off, but when compiling with PGI's pgicpp using -mp for OpenMP support, it automatically uses the --no_exceptions option: everywhere in my code with a "throw" statement generates a fatal compiler error. ("support for exception handling is disabled")
Is there a defined macro I can test to hide the throw statements on PGI? I usually work with gcc, which has GCC_VERSION and the like. I can't find any documentation describing these macros in PGI.

So if you ever need to check the version of the GCC C++ compiler that you have installed on your PC, you can do it through the command prompt by typing in the single line, g++ --version, and this will return the result.
g++ command is a GNU c++ compiler invocation command, which is used for preprocessing, compilation, assembly and linking of source code to generate an executable file.
Take a look at the Pre-defined C/C++ Compiler Macros project on Sourceforge.
PGI's compiler has a __PGI macro.
Also, take a look at libnuwen's compiler.hh header for a decent way to 'normalize' compiler versioning macros.

You could try this to see what macros are predefined by the compiler:
pgcc -dM
Maybe that will reveal a suitable macro you can use.
