Add ``autoconf`` helpers for saving and restoring environment variables:
|
||||
|
||||
* ``SAVE_ENV``: Save ``$CFLAGS``, ``$LDFLAGS``, ``$LIBS``, and
|
||||
``$CPPFLAGS``.
|
||||
* ``RESTORE_ENV``: Restore ``$CFLAGS``, ``$LDFLAGS``, ``$LIBS``, and
|
||||
``$CPPFLAGS``.
|
||||
* ``WITH_SAVE_ENV([SCRIPT])``: Run ``SCRIPT`` wrapped with ``SAVE_ENV`` and
|
||||
``RESTORE_ENV``.
|
||||
|
||||
