[Bug-gsl]Not a bug, just another platform on which GSL works fine...

[Maarten De Munck]

Hi all,

I am a mechanical engineering student, and I compiled GSL for use with
my master thesis today. In the thesis, I work (together with the
research group), on a program for sound prediction, using the indirect
Trefftz approach. (Just to let you know what GSL can be used for...)

At the department, we mainly use HP workstations. Our primary C (and
C++) compiler is the HP ANSI C++ compiler. This compiler is extremely
strict about type conversions, and the source code needed two little
changes to compile:

In vector/vector_source.c, line 28:

        const BASE zero = ZERO;

should become

        BASE zero = ZERO;

because this zero is used as a non-const function argument, passed by
address. Probably it is also possible to change the function declaration
somewhere, but this change was faster, and it isn't that dirty.

And in matrix/matrix_source.c, line 25, the same change is needed.

With these two changes, GSL compiles fine with the HP aCC compiler. The
compiler needs the '-AE' flag, to turn the c89 mode on, but that's quite
normal for C programs.

Congratulations with the code: this is the best C code I've ever seen.
(the first time I've seen some kind of templates in C, and you've done
it very nice!)

Groetjes,

    Maarten
