Subject: Separate the modification of GCONV_PATH from the rest of the initialization,
X-Git-Url: https://git.dlugolecki.net.pl/?a=commitdiff_plain;h=9b4b646eafd90dcff38ab9ed9d89bba0a4a8c62d;p=gedcom-parse.git

Separate the modification of GCONV_PATH from the rest of the initialization,
and let it be called before main (necessary because iconv_open will only look
at GCONV_PATH once, and e.g. GTK calls iconv_open very early).
