# gl_FULL_HEADER_PATH(HEADER1 HEADER2 ...)
# ----------------------------------------
# Find the full path to a header file, assuming the header exists.
# If the header were sys/inttypes.h, this macro would define
# FULL_PATH_SYS_INTTYPES_H to the `<>' quoted full path to sys/inttypes.h
# in config.h
# (e.g. `#define FULL_PATH_SYS_INTTYPES_H </usr/include/sys/inttypes.h>').
