[patches] PATCH: Change meaning of NSSWITCH fixed config file variables

[Jim Blandy <jimb@xxxxxxxxxxxxxxxx>]

The patch below seems to make things easier to use; I've committed it.

ChangeLog.eglibc:
2007-09-21  Jim Blandy  <jimb@xxxxxxxxxxxxxxxx>

	* nss/Makefile: Treat OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS and
	OPTION_EGLIBC_NSSWITCH_FIXED_CONFIG as absolute filenames.
	* option-groups.def: Update documentation.
