It's possible, but exactly what macros you look for differs from system
to system. See, for example:

GCC: Common Predefined Macros (macros defined in every port of GCC)
http://gcc.gnu.org/onlinedocs/gcc-3.4.0/cpp/Common-Predefined-Macros.html#Common%20Predefined%20Macros

GCC: System-specific Predefined Macros (how to find system-specific GCC
macros)
http://gcc.gnu.org/onlinedocs/gcc-3.4.0/cpp/System-specific-Predefined-Macros.html#System-specific%20Predefined%20Macros

Microsoft: Predefined Macros
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang/html/_predir_predefined_macros.asp

I usually look for _MSC_VER to identify Microsoft compilers.

Since the answer to your question differs from system to system, you'll
have better luck seeking answers on newsgroups devoted to your
platform/compiler (assuming you can't find the answers in the
documentation).
