[Scons-dev] Problem with LINKCOMSTR variable substitution

[Strand, Kyle J]

I think this is a bug, but I might just be using env.Replace incorrectly, so if someone could let me know what they think I'd appreciate it. I find that variables in my LINKCOMSTR aren't always be properly substituted. For instance, if I define an environment as follows:

env = Environment(LINKCOMSTR = "Linking... ${TARGET.file}",)
env.Replace(LINKCOMSTR = '${LINKCOM}')

....and then I build targets with that environment, I see the following output:

${TEMPFILE("$LINK $LINKFLAGS /OUT:$TARGET.windows $_LIBDIRFLAGS $_LIBFLAGS $_PDB $SOURCES.windows")}

(This is on a Windows machine using MSVC.) In other words, only one level of substitution is done on $LINKCOM, but $LINKCOM itself contains other variables which are not substituted out before printing. The correct command is executed, however.

It also appears that there's the same problem with SHLINKCOMSTR, but it does NOT appear to be a problem with other environment variables (CXXCOMSTR, etc).
