I don't have access to either an HP-UX or AIX system, but there may be an
additional complication on Solaris 2 and IRIX 6: unlike e.g. glibc and
maybe HP-UX and/or AIX, both systems define both _Complex_I and
_Imaginary_I and I in terms of the latter. I'm not certain if we can just
throw the _Imaginary_I/imaginary definitions away and use
#define _Complex_I (__extension__ 1.0iF)
instead or we must/should maintain the imaginary related definitions.
There seems to be some discussion around having removed
imaginary/_Imaginary_I in C99 TC2, but I'm not sure what the resolution
was.
I've manually done the former by dropping a hacked complex.h into
gcc/include-fixed and as expected the bootstrap finished. If this is the
proper way to go, I can implement this via fixincludes.
