ICU_LINK doesn't work

[Andrey Semashev]

I'm trying to compile Boost.Regex with ICU 3.4 and MSVC 7.1. The ICU library in my case has a nonstandard directory layout like this:

  icu
   |
   |->include
   |   |
   |   |->layout
   |   |->unicode
   |
   |->win32
       |
       |->lib

So the library binaries are in icu/win32/lib instead of the standard icu/lib. I tried to use ICU_LINK environment variable, like bjam suggests (note, I use Cygwin to build the library):

export HAVE_ICU=1
export ICU_PATH="$PATH_TO_ICU/icu"
export ICU_LINK="/LIBPATH:$PATH_TO_ICU/icu/win32/lib icuuc.lib icuin.lib icudt.lib"

However, it seems this variable has no effect, the parameters in ICU_LINK are not seen in the linker command line.

What I eventually came up with was to explicitly specify $ICU_LINK in linkflags for bjam when building Boost.Regex.

The patch fixes the Jamfile so that it passes ICU_LINK flags to the linker
