Re: [ft] Freetype2 compilation error

[suzuki toshiya]

Dear Amit,

I attached a small C-like source for /bin/cpp,
it checks the maximum bitshift operation that
C preprocessor can work well. Please execute

/bin/cpp ./cpp-bitshift-test.c

and send me its output.

For example, the output by GCC on Linux/i386
finishes as:
-----------------------------------------------
[snip]
# 2 "/dev/shm/cpp-bitshift-test.c" 2
/dev/shm/cpp-bitshift-test.c:3:37: warning: integer constant is too large for 
its type [enabled by default]
# 27 "/dev/shm/cpp-bitshift-test.c"
The max bitshift by C preprocessor would be 63
-----------------------------------------------
so we can expect that cpp macro like ((ULONG_MAX >> 63) == 0)
can be used to check the size of unsigned long.

Regards,
mpsuzuki
