This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Version 0.3.10 (2007-03-20)
---------------------------
- Added win32/winutil.h to tarball - fixes bug #1629945
- Fixed presentation of --enable-debug in configure script
- Added twolame_encode_buffer_float32_interleaved()

Version 0.3.9 (2006-12-31)
--------------------------
- Fix for Windows in simple frontend: open files in binary mode
* thanks to Kurien Mathew
- (libtwolame) Fixed energy level support
* thanks to Staale Helleberg
- Nows displays the version number of libsndfile in frontend
* as suggested by Elio Blanca
- Changed documentation build system, so you have to run it manually
- Buffer overrun fix in new_extension()
- (libtwolame) Added warning that DAB support is still broken
- (libtwolame) Added twolame_get_framelength() to return number of bytes per frame
- Added TWOLAME_SAMPLES_PER_FRAME macro, clarifying that there are
always 1152 samples per frame in Layer 2
- Frontend now displays extra information
* Duration of input file (if known)
* Total number of frames to be encoded and percentage complete
* The filesize of the output file
- Cleaned up source files so that it is consistent and all uses tabs (tab width 4)
Version 0.3.8 (2006-06-19)
--------------------------
- (libtwolame) Fixed CRC protection
- More code tidying
- pkg-config is no-longer required (but is recommended)
- frontend now has the exectuable suffix appended to filename
- added -std=c99 to the compiler options
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.
For example, "make show-buildlink3" in fonts/Xft2 displays:
zlib
fontconfig
iconv
zlib
freetype2
expat
freetype2
Xrender
renderproto
TwoLAME is an optimised MPEG Audio Layer 2 (MP2) encoder based on
tooLAME by Mike Cheng, which in turn is based upon the ISO dist10
code and portions of LAME.
Features added to TwoLAME:
* Fully thread-safe
* Static and shared library (libtwolame)
* API very similar to LAME's (for easy porting)
* Frontend supports wider range of input files (using libsndfile)
* automake/libtool/pkgconfig based build system
* C99 compliant
