* INSTALL
* external/Makefile
+ external/libhpdf/*
+ external/libpng/*
+ Added libharu and libpng to Harbour repository.
Now it's possible to use libhpdf as static lib on all
platforms. This is useful because this lib isn't yet part
of Linux distros.
libpng is only built for win/dos/os2 platforms.
It's possible to override libpng location by using
HB_INC_LIBPNG envvar.
* contrib/hbhpdf/Makefile
+ Look for libharu headers in /external dir.
* external/sqlite3/Makefile
- Disabled for bcc. Latest sqlite3 version breaks with this compiler:

|
|
* This code implements the MD5 message-digest algorithm.

|
* The algorithm is due to Ron Rivest. This code was

* This code is in the public domain; do with it what you wish.

|
* This code has been tested against that, and is equivalent,

* except that you don't need to include two pages of legalese
|

* with every copy.
|
|

|
|
* To compute the message digest of a chunk of bytes, declare an
|
|
* MD5Context structure, pass it to MD5Init, call MD5Update as
|
|
* needed on buffers full of bytes, and then call MD5Final, which
|
|
* will fill a supplied 16-byte array with the digest.
