-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.
