It seems that libtool is set up to strip unrecognized flags unless
using something like -Wc,flag. Can anyone give me a brief answer as
to why? I often find myself going through hoops to get flags past
The reason for the odd behavior is that libtool needs to know which
options should be applied to the compiler, and which should be applied
to the linker. Only libtool knows if the compiler is used for
linking, or if the system linker is used to link. If the system
linker is used to link, then only linker options are safe to apply.
