Description
I tried to compile BOINC API for 32-bit Linux, being on a 64-bit Linux machine. Using configure --enable-bitness=32 doesn't work; it compiles 64-bit code anyway (I didn't let make run to completion; I aborted it as soon as I saw a few files being compiled without any 32-bit flag).
I found the problem is the SAH_OPTION_BITNESS macro (defined in m4/sah_select_bitness.m4) adds -m32 to CFLAGS, but not to CXXFLAGS, so C code would be compiled as 32-bit but C++ code wouldn't.
Another minor bug: if the macro detects -m32 works, it prints "Selecting 32 bit model... -m32" but then prints "failed" on the next line anyway. The printing of "failed" is done always, instead of in the 'else' clause of checking if -m32 works.
A belated happy birthday for this bug report!
