protect $$s for bash.

Fix the 'set -e' business for subdirectories.  Too late for 2.08
unfortunately.

set $(exeext) to empty, since it's currently set to @exeext@ and
there's nothing in the configure script to pass in its real value.

I'll move the tag on this file for 2.08, it can be fixed properly later.

- do $(SCRIPT_SUBST) properly for shell scripts.
- don't bomb out if the rmdir fails when cleaning split_objs
directories.

add HappyProjectName etc. variables.

Use exeext; removed non-#! support for cygwin32 (no longer needed)

Added exeext (cygwin32b18-specific);turn off splitting for profiled libs

remove $(basename ..) from $(GhcLibHcOpts).

remove last bit of deforester.

stop-on-error behaviour for recursive rules

nuke GhcBuildeeVersion (which wasn't used anywhere) and
GhcBuilerVersion (which was potentially wrong and not used anywhere).

update version numbers.

$(WithHappyHc) = $(WithGhcHc) is a more sensible default.

add $(WithHappyHc) variable, to be set in build.mk (defaulting to
ghc-0.29, same as $(WithGhcHc)).

remove superfluous braek introduced in rev.1.16.

build and install Happy by default.

runtest rule is the wrong way around.  Not that it ever gets used.

Added TAGS_HS_SRCS and TAGS_C_SRCS

Improved TAGS support

Added TYPE_TIMEZONE

version nos upped to 2.06; added -O to GhcLibHcOpts; added HAPPY_VERSION

fix: cleaning out split dirs pre re-make did not work

ranlib installed libraries if needs be

move the happy option-setting bit to the right place.

Add -1.2 to the happy options if we're using a GHC less than version
2.0.

Added suffix rules, option variables, etc for greencard

Version numbers bumped up in preparation for 2.05

Added hooks to have multiple object suffixes for make depend

Add entry for HAVE_ALTZONE

Automatically set GhcWithNativeCodeGen

More portable use of grep

Added .hs -> .hc rule

removed: HostPlatform_GNU; added: HostOS_Full

LIT2TEXT suffix rule fixed

Reverted back to use of #! in perl scripts on non-cygwin32 platforms

Improved test for how to invoke makedepend script on Haskell source

Auxillary to let autoheader do its job (ToDo: add mk support for this)

updated for 2.04; new variable: HostPlatform_GNU

hash-bang scripts

removed repeated use of .PRECIOUS
