## This is supposed to be a generalised version of LYX_STL_STRING_FWD
|
|
## It almost works. I've tried a few variations but they give errors
|
|
## of one sort or other: bad substitution or file not found etc. The
|
|
## actual header _is_ found though and the cache variable is set however
|
|
## the reported setting (on screen) is equal to $ac_safe for some unknown
|
|
## reason.
|
|
## Additionally, autoheader can't figure out what to use as the name in
|
|
## the config.h.in file so we need to write our own entries there -- one for
|
|
## each header in the form PATH_HEADER_NAME_H
