Thanks to Ian's suggestion, I was able to push past the conversion
error with macro.c. Unfortunately two more problems have surfaced.
The first happened after "fixing" the macro.c issue; the build
continued but then threw a number of undefined errors for functions
contained in libcpp when trying to build part of the cc1 binary. I
don't have the exact functions; I'll post them if they show up again.
Since I'd been making some changes to internal.h and files.c in the
interim source directory, I ran make distclean in the build directory,
copied the original files over to the interim source, and re-ran
configure.
The second error appears after the above; make fails after the following error
../../gcc-4.8/libcpp/files.c: In fuction 'bool
read_file_guts(cpp_reader*, _cpp_file*)':
../../gcc-4.8/lilbcpp/files/c:723:27: error: cannot convert 'long
long int*' to 'off_t* {aka long int*}' for argument '7' to 'unsigned
char* _cpp_convert_input(cpp_reader*, const char*, unsigned char*,
size_t, size_t, const unsigned char**, off_t*)'
I've done some research on this error while trying to resolve this;
for Android, off_t is always 32bits and there is an off64_t, but I
don't know if the error I'm getting above is because of this fact or
something related to the problem I was having with macro.c.
Any help is appreciated.
