Re: Can't build TclTLS 2.0b1

Alan,
A shot in the dark...from the gcc docs:
If a standard system include directory, or a directory specified with `-isystem', is also specified with `-I', the `-I' option will be ignored. The directory will still be searched but as a system directory at its normal position in the system include chain. This is to ensure that GCC's procedure to fix buggy system headers and the ordering for the include_next directive are not inadvertently changed. If you really need to change the search order for system directories, use the `-nostdinc' and/or `-isystem' options.
Key phrase - "-I option will be ignored"
So I'm guessing that /usr/include is already in the default system include search path and therefore gets ignored when specified as the -I option. Additionally, /usr/local/include appears before /usr/include in the default search path. That might explain what you are seeing.
