That is an old problem. If you look in sendmail's "test/Results",
you can see seteuid() problems going back to linux-1.2.13 (11/2/95).
I actually tripped over that fairly recently since it mostly effects
local->local email and submitted this patch to the sendmail folks:
The "POSIX" comment has to do with the way sendmail guesses default
capabilities and why it favors seteuid() over setreuid() by default.
Should be fixed > sendmail-8.9.1. (:
As a side note, has anyone else tried to recompile egcs-1.0.3a under
glibc-2.0.95? In bootstrapping my homebrew distribution I got hung up
in there with errors in egcs's libio.h header. If I don't hear from
anyone I'm going to try a egcs snapshot and then spot-compile a few
more programs to see if it is egcs or a more general problem. I just
rebuilt from scratch the day before against linux-2.1.112, so moving
from -2.0.94 to -2.0.95 should have been the only new variable.
I get a lot of these:
/h/src/jk1/egcs-1.0.3a/BUILD/../libio/libio.h:270:
invalid exception specifications
/h/src/jk1/egcs-1.0.3a/BUILD/../libio/libioP.h:453:
invalid exception specifications
Where the line #s in libio.h & libioP.h are:
libio.h: 270 271 272 273
libioP.h: 94 100 107 119 126 133 143 156 164 170
176 194 201 209 219 226 233 238 453
Those happen a fair way into the compile (libraries/libiberty).
