Bug ID: 61649
Summary: fixincludes update for solaris___restrict in
sys/feature_tests.h on Illumos
Product: gcc
Version: 4.7.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: richard at netbsd dot org
Created attachment 33031

patch to existing fixincludes/inclhack.def from gcc-4.7.3
Due to an update to sys/feature_tests.h as indicated here
(https://illumos.org/issues/2941), Illumos has "broken" the fixincludes
solaris___restrict hack as is evident by the current result in
$PREFIX/gcc47/lib/.../include-fixed/sys/feature_tests.h
/*
* The following macro defines a value for the ISO C99 restrict
* keyword so that _RESTRICT_KYWD resolves to "restrict" if
* an ISO C99 compiler is used and "" (null string) if any other
* compiler is used. This allows for the use of single prototype
* declarations regardless of compiler version.
*/
#if (defined(__STDC__) && defined(_STDC_C99)) && !defined(__cplusplus)
#ifdef __cplusplus
#define _RESTRICT_KYWD __restrict
#else
#define _RESTRICT_KYWD restrict
#endif
#else
#define _RESTRICT_KYWD
#endif
The attached patch seem to work around this by allowing both the standard and
the Illumos forms to be updated.
The test/base/sys/feature_tests.h patch is as follows:
