I want to add this function to the aclocal.m4
How do I do it.
Are you using automake? If so, just stick the function in a file in the
same directory as where you tell 'aclocal -I dir' to look. If not, just
paste it in.

I am quite happy with aclocal, but and the default macros,
Is there anyway I can add a directory, and still have aclocal use new macro.
Yes, as Eric indicated: you can do it like this:
- create a m4/ subdirectory of your top source directory,
- create a file m4/mymacro.m4 with the macro(s) contents,
- add the line
ACLOCAL_AMFLAGS = -I m4
to the toplevel Makefile.am file,
- optionally also add the line
AC_CONFIG_MACRO_DIR([m4])
to the configure.ac file
and rerun 'autoreconf -v'. If your configure.ac file uses the macro,
then it should now be picked up from the file in the m4 directory.
Have fun,
Ralf

autoreconfig -v is run, the new configure file is made, but
I get this configure error
checking for gethostname function prototype in unistd.h... ./configure:
line 3828: syntax error near unexpected token `newline'
./configure: line 3828: `*GNU*'
Any ideas.
