Instead, test for tool capabilities. For example, suppose you want to use the 'restrict' keyword if available. Don't check the compiler's version number; instead, compile a little program that uses 'restrict', and see whether the compilation succeeds. > 3) Say the OS has sed 2.95, could the application's GNU dependencies would > be self-contained with the correct source to compile for the platform, > otherwise use the existing version? It could be done, yes. However it is a bit much to copy 'sed's source code around.
