annotate aclocal.m4 @ 323:29de6a1c4538
Fixed an important bug with folded headers!
g_strconcat() returns a *copy* of the string, but hdr->value still
pointed to the old header (which probably was a memory leak, too).
If the folded part had been quite small it was likely that the new
string was at the same position as the old one, thus making everything
go well. But if pretty long headers were folded several times it was
likely that the new string was allocated somewhere else in memory,
thus breaking things. In result mails to lots of recipients (folded
header) were frequently only sent to the ones in the first line. Sorry
for the inconvenience.

| 224 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets | |
| 225 # $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to | |
| 226 # `$srcdir', `$srcdir/..', or `$srcdir/../..'. | |
| 227 # | |
| 228 # Of course, Automake must honor this variable whenever it calls a | |
| 229 # tool from the auxiliary directory. The problem is that $srcdir (and | |
| 230 # therefore $ac_aux_dir as well) can be either absolute or relative, | |
| 231 # depending on how configure is run. This is pretty annoying, since | |
| 232 # it makes $ac_aux_dir quite unusable in subdirectories: in the top | |
| 233 # source directory, any form will work fine, but in subdirectories a | |
| 234 # relative path needs to be adjusted first. | |
| 235 # | |
| 236 # $ac_aux_dir/missing | |
| 237 # fails when called from a subdirectory if $ac_aux_dir is relative | |
| 238 # $top_srcdir/$ac_aux_dir/missing | |
| 239 # fails if $ac_aux_dir is absolute, | |
| 240 # fails when called from a subdirectory in a VPATH build with | |
| 241 # a relative $ac_aux_dir | |
| 242 # | |
| 243 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | |
| 244 # are both prefixed by $srcdir. In an in-source build this is usually | |
| 245 # harmless because $srcdir is `.', but things will broke when you | |
| 246 # start a VPATH build or use an absolute $srcdir. | |
| 247 # | |
| 248 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, | |
| 249 # iff we strip the leading $srcdir from $ac_aux_dir. That would be: | |
| 250 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` | |
| 251 # and then we would define $MISSING as | |

| 253 # This will work as long as MISSING is not called from configure, because | |
| 254 # unfortunately $(top_srcdir) has no meaning in configure. | |
| 255 # However there are other variables, like CC, which are often used in | |
| 256 # configure, and could therefore not use this "fixed" $ac_aux_dir. | |
| 257 # | |
| 258 # Another solution, used here, is to always expand $ac_aux_dir to an | |
