configure-generated *.in's

[J.T. Conklin]

Roger Leigh's AC_CONFIG_PKGCONFIG_IN macro from the autoconf macro
archive generates a *.pc.in files.  The intent seems to be for the
*.pc.in file to be post-processed by AC_CONFIG_FILES to expand any
@macros@, and then the resulting *.pc file can be installed for use 
by pkg-config.

However, if I add foo.pc to AC_CONFIG_FILES, autoconf complains that
foo.pc.in does not exist (which it does not).  However, if I omit it,
foo.pc.in is generated at configure-time, but foo.pc is not.

Does anyone have any clue how to use this macro?
