2365 functions: install_predefs and initialize_dependency_output.
2366 Use path_include for C_INCLUDE_PATH and friends as well as

2371 (append_include_chain): Brought over from cppfiles.c. Mark
2372 dirs as system include dirs if and only if appending to
2373 system include path. If opts->verbose, print a notice when a

7934 out the definition. It was being called incorrectly and at
7935 the wrong times. Until a VMSie can look at this, it's better

8047 The strategy we now use is to pre allocate the top_elt along
8048 with the EH context so that each thread has its own top_elt.
8049 This is necessary as the dynamic cleanup chain is used on the
8050 top element of the stack and each thread MUST have its own.
