megatest fallout

[Ralf Wildenhues]

Greetings,

time for some (late) spring cleaning in gnulib.  I sent a bunch of mails
with patches that fall off of
  CC='gcc -Wall -Werror -fno-builtin' gnulib-tool --megatest 

to this list and autoconf-patches.  In the end I get down to about a
handful of missing bits:

- getloadavg/configure.ac needs
    AC_CONFIG_LIBOBJ_DIR([gllib])
  added early in the file.

- ./bison-i18n/configure.ac needs
    AM_GNU_GETTEXT([external])
  somewhere, and a gettextize call.

- These leftover warnings:
| argp/gllib/argp-help.c:465: warning: comparison is always true due to limited 
range of data type
| argp/gllib/argp-help.c:866: warning: comparison is always true due to limited 
range of data type

- This leftover false test result:
| configure:54994: checking for working re_compile_pattern
| configure:55122: gcc -Wall -Werror -fno-builtin -o conftest -g -O2
| -Wl,--as-needed conftest.c -lm  >&5
| cc1: warnings being treated as errors
| conftest.c: In function 'main':
| conftest.c:481: warning: pointer targets in assignment differ in signedness

where line 481 is line 81 in m4/regex.m4 (gl_REGEX):
|           regex.translate = folded_chars;

- Failures that stem from the incomplete HAVE_CONFIG_H transition,
  including but certainly not limited to these files:
  base64.c, argp-help.c, xvasprintf.c, check-version.c, hmac-md5.c,
  memxor.c, hmac-sha1.c

Hope that helps.

Cheers,
Ralf
