2.5.31 assumes snprintf()

[Hans-Bernhard Broeker]

Hello, flexers,

at least as of 2.5.31, flex calls snprintf() in two places (one of which
is in yacc source, so it appears twice in the cscope dump below):

0 parse.c format_warn3 125 snprintf( fw3_msg, MAXLINE,(fmt), (a1), (a2) );\
1 parse.y format_warn3 115 snprintf( fw3_msg, MAXLINE,(fmt), (a1), (a2) );\
2 regex.c regmatch_cpy 102 snprintf (dest, regmatch_len(m), "%s", src +
                           m->rm_so);

Please note that while common, snprintf() is by far not a reliably
available function on all target platforms.  This prevents building of
flex-2.5.31 on Digital Unix 4.0, and DOS/DJGPP 2.03, to name just two
affected platforms I know of.

I would count this as one of the things that need to be checked out
before a 2.6 release.

BTW: does anyone of the developers even read the Bug Tracker and other
entries at flex' SourceForge pages?  I ask because not a single of the bug
reports there has ever been 'closed', 'deleted' or otherwise finalized, as
far as can be seen...
