FYI: Reply from HP-UX

Just a quick note that (32-bit) git builds on HP-UX are now downloadable
here:

http://hpux.connect.org.uk/hppd/hpux/Development/Tools/git-1.5.3.8/

A lot of dependencies listed (though I'm not convinced you need them all!)
and the revised changes list is as follows:

* Documentation/Makefile:
  - Use /usr/local/bin/perl rather than just perl.

* Makefile:
  - Use "include" to include config.mak.autogen, rather than "-include"
    (the latter doesn't seem to include the file!).
  - install-sh requires a space between its -m parameter and the mode
    value (so doesn't like -m755 for example).
  - install-sh only installs one file at a time, so create a for loop
    to install $(ALL_PORGRAMS).
  - Strip the installed $(PROGRAMS), git and git-merge-subtree binaries.
  - "gmake clean" no longer deletes config.mak.autogen, to avoid a second
    "gmake clean" failing (because that include file won't be there then).

* builtin-fetch--tool.c, fast-import.c and unpack-trees.c:
  - Use of "int a=a;"-type statements is totally bizarre, even if it's
    strictly correct. Changed them to =0 (or =(cast_type)NULL) to avoid
    HP ANSI C warnings about uninitialised variables.

* config.mak.in:
  - Pass LDFLAGS, INSTALL and NO_UNSETENV to config.mak.autogen.

* configure:
  - Cache file is now config.cache, rather than /dev/null.
  - Set up an HP-UX override section, including:
    * Set prefix to /usr/local.
    * Put /usr/local/bin in the front of the PATH.
    * If Itanium, set libdir to /usr/local/lib/hpux32.
    * Compile with "cc -O -I/usr/local/include -Dinline= -DFLEX_ARRAY=1 -AC99".
    * Set LDFLAGS to embed $libdir as a run-time library search path.
    * Set RANLIB to /bin/true.
    * Enable both shared and static library building.
    * Force configure to think HP-UX has no setenv() function.
    * Set NO_UNSETENV so that compat/unsetenv.c will be built.
    * Pick up perl from /usr/local/bin (HP's perl isn't any use).
    * Set INSTALL to run "`pwd/install-sh -c".
  - Pass NO_UNSETENV and INSTALL through to config.mak.autogen.

* daemon.c:
  - Cast 3rd accept() param to (socklen_t *) to avoid an HP ANSI C compiler
    warning.

* git-gui/Makefile:
  - Set INSTALL to "../install-sh -c".
  - install-sh requires a space between its -m parameter and the mode
    value (so doesn't like -m755 for example).

* install-sh (created from scratch):
  - Used to install files.

* Many t/t*.sh files:
  - Use just "diff" to compare results, rather than GNU-diff-only's "diff -u".
  - Similarly, use just "grep" rather then GNU-grep-only's "grep -a".
  - Some parts of a few tests were commented out because they didn't pass
    for other reasons.

* templates/Makefile:
  - install-sh requires a space between its -m parameter and the mode
    value (so doesn't like -m755 for example).
  - Back-to-back tar'ing during "gmake install" doesn't set new timestamps,
    causing our binary packager to fail to include those files. Hence,
    touch all the installed files to the current timestamp to fix this.
