We don't want to mess with all the portability hassles of alloca.
|
||
In particular, most (all?) versions of bison will use alloca in
|
||
their parser. If bison works on your system (e.g. it should work
|
||
with gcc), then go ahead and use it, but the more general solution
|
||
is to use byacc instead of bison, which should generate a portable
|
||
parser. I played with adding "#define alloca dont_use_alloca", to
|
||
give an error if the parser generator uses alloca (and thus detect
|
||
unportable getdate.c's), but that seems to cause as many problems

as it solves. */
