Description Neal D. Becker 2000-10-29 16:36:19 UTC
/usr/include/bits/xopen_lim.h requires INT_MAX be defined, but xopen_lim.h is included before it's defined.

INT_MAX is defined in /usr/lib/gcc-lib/i386-redhat-linux/2.96/include/limits.h

But look what happens:

nbecker:/usr/local/src/Python-2.0/Parser% gcc -g -O2 -Wall -Wstrict-prototypes -I./../Include -I.. -DHAVE_CONFIG_H -c -o node.o node.c -save-temps -H
 ../Include/Python.h
. ../Include/patchlevel.h
. ../config.h
. /usr/lib/gcc-lib/i386-redhat-linux/2.96/include/limits.h
.. /usr/lib/gcc-lib/i386-redhat-linux/2.96/include/syslimits.h
... /usr/lib/gcc-lib/i386-redhat-linux/2.96/include/limits.h
.... /usr/include/limits.h
..... /usr/include/features.h
...... /usr/include/sys/cdefs.h
...... /usr/include/gnu/stubs.h
..... /usr/include/bits/posix1_lim.h
...... /usr/include/bits/local_lim.h
....... /usr/include/linux/limits.h
..... /usr/include/bits/posix2_lim.h
..... /usr/include/bits/xopen_lim.h

See?  xopen_lim.h is included before limits.h is finished, and before INT_MAX is defined.
