-pedantic flag and warnings

[Vincent Lefevre <vincent@xxxxxxxxxx>]

The configure.in file contains:

if test x$GCC = xyes -a $mutt_cv_warnings = yes; then
        CFLAGS="-Wall -pedantic $CFLAGS"
fi

Is there a reason to use the -pedantic flag in C90 mode whereas Mutt
does not conform to ISO C90?

For instance, I get the following warnings:

copy.c: In function 'mutt_copy_header':
copy.c:473: warning: ISO C90 does not support the 'll' printf length modifier
copy.c: In function '_mutt_copy_message':
copy.c:582: warning: ISO C90 does not support the 'll' printf length modifier
copy.c: In function 'copy_delete_attach':
copy.c:825: warning: ISO C90 does not support the 'll' printf length modifier
