[Pkg-tcltk-devel] Bug#440683: tcl8.4 strtod + fixstrtod confusion leads to symbol clash

[Ian Jackson]

Package: tcl8.4
Version: 8.4.15-1
Tags: patch

I was trying to build tcl from source and for reasons I haven't
identified yet, it decided that it needed both compat/strtod.c and
compat/fixstrtod.c.

However, if this happens config.h #defines strtod to fixstrtod.  The
result is that strtod.c generates a strtod.o which defines fixstrtod,
and this leads to a multiply defined symbol.

To fix this I made the following change (but I still need to
investigate why configure isn't working properly).

Regards,
Ian.
