Hello, I noticed that if I give g++ the prototypes for bsearch as listed in the 2003 standard, it errors out saying that the 2 declarations conflict:
extern "C" void *bsearch(const void *key, const void *base, size_t nmemb, size_t size, int (*compar)(const void *, const void *)); extern "C++" void *bsearch(const void *key, const void *base, size_t nmemb, size_t size, int (*compar)(const void *, const void *)); The same is true for qsort. I believe the compiler is supposed to distinguish between the 2 versions according to the linkage of compar. Even if you don't want to distinguish functions according to linkage, g++ should be able to accept a declaration that is written in the standard. -- Summary: g++ does not distinguish functions with C and C++ linkage Product: gcc Version: 4.1.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: marc dot glisse at normalesup dot org GCC host triplet: i486-linux-gnu http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30062
