version 0.9.25:

- first support for x86-64 target (Shinichiro Hamaji)
- support µClibc
- split tcc.c into tcc.h libtcc.c tccpp.c tccgen.c tcc.c
- improved preprocess output with linenumbers and spaces preserved
- tcc_relocate now copies code into user buffer
- fix bitfields with non-int types and in unions
- improve ARM cross-compiling (Daniel Glöckner)
- link stabstr sections from multiple objects
- better (still limited) support for multiple TCCStates

version 0.9.24:

- added verbosity levels -v, -vv, -vvv
- Accept standard input as an inputstream (Hanzac Chen)
- Support c89 compilers other than gcc (Hanzac Chen)
- -soname linker option (Marc Andre Tanner)
- Just warn about unknown directives, ignore quotes in #error/#warning
- Define __STDC_VERSION__=199901L (477)
- Switch to newer tccpe.c (includes support for resources)
- Handle backslashes within #include/#error/#warning
- Import changesets (part 4) 428,457,460,467: defines for openbsd etc.
- Use _WIN32 for a windows hosted tcc and define it for the PE target,
  otherwise define __unix / __linux (Detlef Riekenberg)
- Import changesets (part 3) 409,410: ARM EABI by Daniel Glöckner
- Some in-between fixes:
  TCC -E no longer hangs with macro calls involving newlines.
  (next_nomacro1 now advances the read-pointer with TOK_LINEFEED)
  Global cast (int g_i = 1LL;) no longer crashes tcc.
  (nocode_wanted is initially 1, and only 0 for gen_function)
  On win32 now tcc.exe finds 'include' & 'lib' even if itself is in 'bin'.
  (new function w32_tcc_lib_path removes 'bin' if detected)
  Added quick build batch file for mingw (win32/build-tcc.bat)
  Last added case label optimization (455) produced wrong code. Reverted.
