True - it fixes at a wrong position. It's just that the gcc which is
installed when bootstrapping Linux doesn't understand the switch
-std=(gnu99|c99) and this is why the build breaks. I have attached a
patch with require gcc 3+ - I have tested it on Linux and it builds,
however when building the package it says:

=> Registering installation for libiconv-1.10nb3
libiconv-1.10nb3 requires installed package gcc3-c-3.3.6
libiconv-1.10nb3 requires installed package gcc3-c++-3.3.6
===> Building binary package for libiconv-1.10nb3
Creating package /usr/pkgsrc/packages/All/libiconv-1.10nb3.tgz
Using SrcDir value of /usr/pkg
Registering depends: gcc3-c>=3.3.5nb1 gcc3-c++>=3.3.5nb1.

I think that's pretty heavy stuff here for the embedded platforms. iconv
is a handy tool for the shell to convert files, however forcing them to
install a compiler of that size is just maybe not what they want to.
I'll hope I am missing something of the documentation - so I can set gcc
3+ only for building but not as an installation requirement.

What I am still missing - in the original Makefile c99 is specified.
It's not needed on the bootstrap of Linux to build correctly, just c is
needed. Maybe it's a better idea to just skip the c99 - or is it needed
for higher versions of gcc (I am still in the worlds of gcc-2.95, I
suppose)? This might save a horror of dependencies - if I don't missed
parts of the documentation.

Thanks and Regards
