This is bug 19541, but being reported against 4.3.0. Still a problem in 4.3.using Debian unstable packages gcc --version gives gcc-4.3 (Debian 4.3-20080116-1) 4.3.0 20080116 (experimental) [trunk revision 131577]
Can we either get the "ignore-source-dir" patch added to the mainline, or else remove the "-I- is deprecated" warning? Clearly there are uses for -I-, as the mailing list thread shows. -- Summary: Bug 19541 is still not resolved in 4.3.0 Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: preprocessor AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ISPARRY at BROCADE dot COM http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34857
