+       Changes to aslink (All the changes are marked with 'JCF'):
+
+       * \sdcc\as\mcs51\aslink.h: External definition of sflag and
+       summary().
+
+       * \sdcc\as\mcs51\lkarea.c: Computes the size of area BSEG_BYTES from
+       area BSEG.  Also moves, if possible, the DATA area down into the internal
+       ram so more space is available.
+
+       * \sdcc\as\mcs51\lkdata.c: Definition of memory summary output flag
+       sflag.
+
+       * \sdcc\as\mcs51\lklist.c: For the BSEG area report the size in bits,
+       not bytes.  Function summary() which creates a memory usage summary
+       file with extension .mem.  Reports of overlaping stack and small stack
+       size.  If the space for the stack is less than 16 bytes aslink trows a
+       warning.
+       
+       * \sdcc\as\mcs51\lkmain.c: Creation of some of the default areas for
+       the 8051.  Option 'y' for memory summary output file.
+
+       Changes to sdcc (All the changes are marked with 'JCF'):
+
+       * \sdcc\src\SDCCglobl.h: External definition of RegBankUsed[4].
+
+       * \sdcc\src\SDCCglue.c:  If a register bank is used, creates an
+       overlaying area for it (uses RegBankUsed[4]).
+
+       * \sdcc\src\SDCCmain.c: Definition RegBankUsed[4]; marks register
+       bank zero as used by default.  By default aslink locates the stack
+       (equivalent to --stack-after-data).  Pass option 'y' to aslink for
+       the creation of the .mem file.  Delegates the allocation of data area
+       to aslink (it is not longer 0x30 by default).  If --stack-loc passes
+       the begining of the stack area to aslink.
+
+       * \sdcc\src\SDCCmem.c:  If a register bank is used, marks it so
+       glue() in SDCCglue.c creates an area for it.
