of qmail-lspawn, qmail-newmrh, qmail-newu, qmail-pop3d, qmail-popup,
qmail-rspawn, and qmail-smtpd. This fixes two known bugs:
- qmail-smtpd can be crashed by a client sending a sufficiently
long (e.g. 2GB) header line in an email.
- qmail_lspawn, qmail-newmrh, qmail-newu, and qmail-rspawn might
crash or otherwise misbehave on hosts with a smaller "int" type
than "char *" type, e.g. 64-bit hosts with 32-bit "int"s.
The other changes are unlikely to have any effect, except possibly on
unusual architectures and/or in the presence of rare optimizations.
This is Version 1 of this patch. It adds the changes to
cdbmake_add.c, spawn.c, and, correspondingly, Makefile, which pertain
to the second bug listed above.
