This patch was contributed by Daniel Simon of the U of Stuttgart. It
allows building gnat-gdb on sparc-sun-linux. Here is what Daniel
says:
> is there a reason for not having a gnat-gdb on Debian/Sparc?
>
> Yesterday, I downloaded the source package for gnat-gdb and built a
> binary package. It almost compiled without intervention; I had to
> modify one file of the package (replace an included system header by
> its contents, commenting out parts of the contents. I don't actually
> understand what gcc wants from me.)
>
> If you are interested, I can mail you the modified sources.
I amended Daniel's patch to make it minimal.
For more details, see Debian bugs #274694, #274906 and #287484.
