[PATCH 0/2] incpath, Fortran: Fix memory leak in gfc_add_include_path

Hi! In order to fix this very minor leak, we need a knob to free all cpp_dirs that were added. This adds a free_cpp_dirs() to gcc/incpath and needs review from some global maintainer or maybe libcpp maintainer for this hunk. Bootstrapped and regtested on x86_64-unknown-linux without regressions.

From: Bernhard Reutner-Fischer gcc/fortran/ChangeLog: PR fortran/68800 * cpp.h (gfc_cpp_free_cpp_dirs): New declaration. * cpp.c (gfc_cpp_free_cpp_dirs): New definition. (gfc_cpp_add_include_path, gfc_cpp_add_include_path_after): Add comment. *

[PATCH 1/2] Add free_cpp_dirs()

From: Bernhard Reutner-Fischer gcc/ChangeLog: * incpath.c (free_cpp_dirs): New function. * incpath.h (free_cpp_dirs): Ditto. --- This adds a helper to allow the fortran FE to free it's include dirs. Bootstrapped and regtested without new regressions on x86_64-unknown-linux. Ok
