2 Questions:

What do you mean by "flagged"? Do you get an error or warning? If so, could you post the message?
Is this code part of the configure script itself, or part of the package source?

Quote from the GCC documentation

Quote:

__GNUC__
__GNUC_MINOR__
__GNUC_PATCHLEVEL__
These macros are defined by all GNU compilers that use the C preprocessor: C, C++, Objective-C and Fortran. Their values are the major version, minor version, and patch level of the compiler, as integer constants. For example, GCC 3.2.1 will define __GNUC__ to 3, __GNUC_MINOR__ to 2, and __GNUC_PATCHLEVEL__ to 1. These macros are also defined if you invoke the preprocessor directly.

So your example seems to be a cheap trick to check the compiler version. The reason might be that there are some problems if it's compiled with GCC version 3, and this code disables/enables some compiler features or code parts that caused that problem.
