Building g++ for target x86_64-pc-mingw32 currently fails. Here is the description from Kai Tietz, along with his proposed patch:
An interesting issue is that there is problem related that in c case the type char * const[] is not equivalent to type char *const *. Is this done by intention ? For the w64 target the parameter of exec(??) methods are using 'const char * const *' but gcc uses the type 'char * const []' for argp and envp arguments. In earlier versions the types were equivalent. See other report: http://gcc.gnu.org/ml/gcc-help/2007-10/msg00008.html So I suggest the following patch for w64 in libgcov.c: ChangeLog: 2007-10-02 Kai Tietz <[EMAIL PROTECTED]> * libgcov.c: (__gcov_execve): Special case for x86_64-pc-mingw32.
