Hi folks,

The patch includes basically two changes:

* Detection of big endian on HP-UX otherwise SHA1 calc is broken
* Detection of linking style with HP aCC

> export PREFIX=/opt/ports
> export LIBDIR=$PREFIX/lib/hpux32
> export CC=/opt/aCC/bin/aCC
> export CXX=/opt/aCC/bin/aCC
> export CONFIGURE="./configure --prefix=$PREFIX --libdir=$LIBDIR"
> export CPPFLAGS="-I$PREFIX/include"
> export LDFLAGS="-L$LIBDIR"
> autoreconf -fi
> $CONFIGURE --with-editor=vim --with-zlib=$PREFIX --with-perl=/usr/bin/perl --with-iconv=$PREFIX \
>   --with-libpcre=$PREFIX --with-gitconfig=$PREFIX/etc/gitconfig --with-gitattributes=$PREFIX/etc/gitattributes \
>   --without-tcltk --disable-pthreads --with-lib=lib/hpux32
> gmake INSTALL=$INSTALL_SH install

Note: I am not subscribed to this list.

Regards,

Michael
