It exists solely to provide access to an ancient, unmaintained version of libstdc++.so for ancient, unmaintained binaries that cannot be rebuilt. It doesn't need to be fast, or have cool CFLAGS. People shouldn't even be using it at all. The people who do use it care about compatibility more than anything else, so successfully compiling it should be taken as the gift that it is. With that in mind, we basically strip all flags. We preserve some existing logic to handle -march= values known to exist in this old gcc, and we continue to support -O levels, but we go no further. It's entirely impractical to support arbitrary flags, since every gcc release adds more flags that old versions don't support and then this fails because GCC 3's internal xgcc build cannot handle them. We also take this opportunity to add a workaround for modern C. New versions of GCC barf on some of the code here because it is not legal C99, but again, the point of this package is to provide legacy compatibility for ancient binaries, so... we assume if it ever worked before, it still works. :) Thus, suppress the errors. In order to suppress the errors, we make a wrapper script around the external compiler (not the xgcc one) so that we can apply flags that only affect modern compilers, and aren't parsed by xgcc which would choke on them due to those flags being too new.
