Removed a last flaw and use `cvs export' instead of `cvs checkout' now.

The first version of a script that allows building rpm packages directly from
CVS.  It currently works for ghc only, but will be extended to cover the
other fptools.

It should work on all rpm-based systems, as I tried to avoid any dependency on
Red Hat systems (as far as I am aware of them).  In particular, the rpm build
process is carried out below /tmp instead of the standard /usr/src/redhat
hierarchy.

By default the cvs head of the anonymous repository is built, but cvs-style -d
-D, and -r options allow to built from a different repository and revision.

[This version is only half tested, because the CVS head seems to not build
anymore today.]

don't use ^ in patterns, Solaris sh barfs on it.

Build System Cleanup
--------------------

This commit is intended to clear the way for automatic RPM building.
In particular, the idea is that 'make install' doesn't build anything,
so you can do

	make install prefix=/some/tmp/prefix

to install everything in /some/tmp/prefix, but leave the hardwired-in
install directories the same.

For scripts that depend on the install dir (currently just the GHC
driver and mkdependHS), we now build two versions: <script>-inplace,
which is used for running the script from the build tree, and
<script>, which is the to-be-installed version.

NOTE: binary distributions are now a little bit trickier to build.
You *must* include the line "BIN_DIST=1" in your build.mk if you
intend to make a binary distribution from the current build tree.
This is because certain scripts have to be built differently, and we
don't rebuild them when doing 'make binary-dist' anymore (since 'make
binary-dist' just does a 'make install' with a re-targetted prefix,
just like the RPM builder).

Other changes

	- the binary-dist machinery is now all in fptools/Makefile
	- removed a gratuitous $(package)-$(version) level of
	  directories from the binary distribution.
	- binary distributions are now placed under the package
	  name, rather than fptools/fptools.
	- various other minor cleanups.

mingw32 support

Patched my previous patch ($ vs $$, && vs if/then/fi). Installing a
Happy binary-dist still only creates a happy and no happy-1.6
executable, but this has very probably nothing to do with my changes.

Two checks for empty file lists added.

No more RAWCPP, thank you.

When installing, append  to entries in PACKAGE_BINS list

Install the docs in $real_datadir, not $datadir.

Updates on the Win32 front

oops, forgot to update bin dist configure for FreeBSD 2.0/3.0 split.

Updated to track aclocal.m4 changes

install-bin:
   * if any of $(VERSION_SYMLINKS_FOR) already exists as a symlink,
     replace it with a new one.

Clarified various cygwin32 install gotchas

- mk-version-symlinks not needed any more: the links are installed by
  the relevant Makefiles.

- install the link from $(package) to $(package-version) in the
  installation directory.

Perform UNC->DOS translation on what bash-cygwin32's pwd returns.

alpha-dec-osf1 and alpha-dec-osf3 are now separate configurations.

Updated cygwin32 details

Added TMPDIR to list of variables prepended to perl & sh scripts.

AC_SUBST(exeext) added (only non-empty under cygwin32)

add note about 'make install-doc' to the message printed after
configuration.

fix script installation *again*.

Finally fix the 'for i in ; do ...' problem.

Some shells have problems with 'for i in ; do ...', so protect the
relevant for loops with 'if test <string>; then ...'.

Replace three 'test ... && ...' sequences with 'if ... then ... fi',
since the test form would fail, causing some non-GNU makes to bomb
out (maybe they invoke sh with -e?).

use PACKAGE_BINS to get the actual binaries to install.

make this Makefile package-independant.

update to version 2.08

protect $$s for bash.

Test for CC and GCC before finding CPP, since GNUCPP depends on
finding GCC to do the right thing.

prepend SED and RAWCPP to all scripts, not just PACKAGE_LIB_SCRIPTS.

do the symlink thing when installing, not in the local tree.

Link ghc to ghc-$(version), not the other way around.  This means that
old versions won't be spammed when a new one is installed.

To go in 3.00

fix dangling backquote in last commit.

Added feature tests for sed and cpp

Upped version number; added SED and RAWCPP for lib_scripts

perl not being added to scripts' top line

update version number, and add stuff to install happy.
