Previous message: Felipe Magno de Almeida: "[Boost-build] Using different assembler and linker (e.g nasm, yasm, ld)"

Hi all,

I have just noticed and fixed an issue with msvc in M11 boost build
snapshot. The original implementation was ignoring user's cflags
specified in <cflags> due to a name clash. The script, I think, was
collapsing both <cflags> and <linkflags> into OPTIONS.

I have restored an earlier implementation which was using USER_CFLAGS
and USER_LINKFLAGS. My version is attached.

Could somebody confirm the issue and validate the fix?

Thanks,
Oleg.
