Summary: preprocessor typo-line #ekse ignored
Product: gcc
Version: 3.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: preprocessor
AssignedTo: unassigned at gcc dot gnu dot org
ReportedBy: mathar at mpia-hd dot mpg dot de
CC: gcc-bugs at gcc dot gnu dot org
GCC build triplet: sparc-sun-solaris2.8
GCC host triplet: sparc-sun-solaris2.8
GCC target triplet: sparc-sun-solaris2.8
If we start some lines of code by using a #if... or #ifndef
or #if define "first" line, a line of the sort #ekse (that is a typo
and was meant to read #else) is ignored and all the code up to the
final #endif is ignored. There should be a syntax warning of the same
kind as if we start the construct with a #if or #ifndef that is "true".

Fix:
No known fix but to check carefully all the #e.. kinds of preprocessor
lines. Note that #if 1 .... #ekse .... #endif reports a syntax
error, and this is what one would also expect from the
#if 0 .... #ekse .... #endif version..

The standard requires that unknown preprocessing directives are ignored. Since
the text inside the non-taken branch of an if directive is ignored except for
breaking it up into preprocessing tokens the example is completely well formed.
