$ libtool --mode=compile --help
[snip]
This mode accepts the following additional options:
[snip]
  -Wc,FLAG          pass FLAG directly to the compiler

$ libtool --mode=link --help
[snip]
The following components of LINK-COMMAND are treated specially:
[snip]
  -Wc,FLAG
  -Xcompiler FLAG   pass linker-specific FLAG directly to the compiler
  -Wl,FLAG
  -Xlinker FLAG     pass linker-specific FLAG directly to the linker

But, often when this happens, it is the fault of a poorly written
configure.ac or Makefile.am.  Where exactly are you seeing an issue?
