[gcompris-devel] gcompris 2.3 solaris

[roberto dircio]

hi, for the first time!

In response to dave lopata's and other's need for
gcompris in solaris, i attach inline files for the
definition of scandir,alphasort,and setenv....
which have been renamed as myscandir,myalphasort...
procedure:
- put myscandir.c and myscandir.h inside src/gcompris 
- include myscandir.h in all files that make use of
scandir,alphasort, or setenv.
- substitute all calls to "scandir", and "alphasort"
to "myscandir" and "myalphasort",
- force them to be built before everything, and voila!

I would suggest rather using non-bsd things for this.
  portability!
