Build failure with GCC 4.2

[Evan Miller]

Hello,

I am a contributor to the MacPorts package manager, with a special interest in 
legacy system support. Our preferred compiler on Mac OS X 10.4 and 10.5 is GCC 
4.2 – but I noticed that the latest release of sed cannot be compiled with GCC 
4.2, as it does not allow pragma directives inside of functions.

If it's not too much trouble, I suggest the patch below, which allows sed 4.9 
to be built successfully with all of our supported compilers.

Thank you so much.

Evan Miller
