Description guichard 1999-10-05 17:17:21 UTC 
Trying to compile amaya 2.1 I get errors like this:

../../thotlib/unicode/ustring.c: In function `ustrcpy':
../../thotlib/unicode/ustring.c:380: void value not ignored
as it ought to be
../../thotlib/unicode/ustring.c: In function `ustrdup':
../../thotlib/unicode/ustring.c:397: void value not ignored
as it ought to be
../../thotlib/unicode/ustring.c: In function `ustrncpy':
../../thotlib/unicode/ustring.c:481: void value not ignored
as it ought to be

When I compile without -O it works fine. I get this behavior
in egcs-1.1.2-12 on intel and egcs-1.1.2-12 & -13 on sparc,
both with 6.0 (sparc with updated kernel). There is no
problem with gcc-2.7.2.3-11 on my redhat 5.1 machine.

Please send the output of gcc -E on the file in question, combined
with the exact command line (e.g "gcc -g -O foo.c") required to
get the error.

Incidentally, I would guess the difference between your two
systems is because of different libraries rather than
gcc2.7 vs. egcs.  But send in the code and I'll have a look.

The glibc headers should fix this in the current rawhide version
