+
+       * src/common/fclose.cxx (fclose): Replace config-dependent use of
+       delete with free(), as the memory had been allocated with malloc.
+
+2007-07-02  Gary Thomas  <gary@mlbassoc.com>
+
+       * src/output/vfnprintf.cxx: Add (char *) casts to make GCC/4.2.x happy.
+
+2007-02-05  Sergei Organov  <osv@javad.com>
+
+       * src/output/vfnprintf.cxx (vfnprintf): while formatting integers
+       in decimal, convert the value to unsigned long from unsigned long
+       long before processing, unless we actually print long long
+       argument. This tremendously speeds-up the formatting.
+
+2007-01-16  Sergei Organov  <osv@javad.com>
+
+       Speed-up [v]s[n]printf() functions by a factor of about 2+. In
+       particular, sprintf(s, "%s", "") becomes faster 2.8 times,
+       printing of every character -- 1.7 times, and, as a result, e.g.,
+       printing of a string of length 50 -- 2.2 times.
+
+       * include/stream.hxx (class Cyg_OutputStream): New ABC.
+       (class Cyg_StdioStream): inherit from Cyg_OutputStream; make
+       the destructor, write(), and get_error() virtual.
+       
+       * src/output/vfnprintf.cxx (vfnprintf): Use ABC Cyg_OutputStream
+       instead of Cyg_StdioStream.
+
+       * src/common/vsnprintf.cxx (class Cyg_VsnprintfStream): New class
+       that specializes Cyg_OutputStream for output to a string.
+       (vsnprintf): Use Cyg_VsnprintfStream for printing to a string.
+
+2006-12-22  Sergei Organov  <osv@javad.com>
+
+       * src/output/vfnprintf.cxx (vfnprintf): Speed-up formatting of
+       decimal integers by replacing modulo operation with multiply and
+       subtract.
+
+2006-09-27  Jonathan Larmour  <jifl@eCosCentric.com>
+
+       * include/stdio.h: Make fpos_t be signed to allow negative
+       SEEK_CUR offsets to fseek().
+       * include/stream.inl (set_position): If SEEK_CUR, then if
+       having to reconcile difference between position and underlying
+       file position, then requested seek position needs adjusting
+       for buffer size.
+       Both above reported and analysed by Ivan Djelic.
+
+2006-09-26  Jonathan Larmour  <jifl@eCosCentric.com>
+
+       * src/common/stream.cxx (read): Only update position after direct
+       reads from I/O system so it's updated by the correct number of
+       bytes.
+       (write): Reset underlying file position if there had been
+       stuff read from the file left in the buffer so the file positions
+       are inconsistent.

        * src/common/fopen.cxx (fopen): Default the open mode to Read
