[PATCH] config.cache problem

[Ralf Wildenhues]

Hi there,

config.cache does harmful things to variables with multi-line values
(but I'm not sure that's the origin of the problem).
This leads to errors such as:

| $ make
| /bin/sh ./config.status --recheck
| running /bin/sh ../configure  -C  --no-create --no-recursion
| configure: loading cache config.cache
| ./config.cache: 141: Syntax error: Unterminated quoted string
| make: *** [config.status] Fehler 2

where the culprit is on line 120 (sic), being wrong-quoted

| libltdl_cv_sys_search_path=${libltdl_cv_sys_search_path='/lib /usr/lib 
/usr/X11R6/lib}

As you could have guessed, this is on linux.  A quick patch which fixes
this is below.  BTW: This one *is* independent of the dash/echo problem
I reported.  There might be other cases like this (e.g. I don't know if
ldconfig output on sunos4* contains newlines), so it might be better to
sanitize this in a common place.

Regards,
Ralf

        * m4/libtool.m4: Remove newlines from lt_ld_extra, so
        Variable can safely be stored in config.cache.
