(What's missing from Ada is all the options shared with C, specifically.) Similarly, on the Fortran output, while the Fortran-specific options are present, the ones shared with C and C++ aren't listed. 4.3 currently gives ---------------------------------- The following options are specific to the language Fortran: -J Put MODULE files in 'directory' -Waliasing Warn about possible aliasing of dummy arguments [...] ---------------------------------- However, 4.2 gives: ---------------------------------- The Fortran front end recognizes the following options: -I, -Wall, -Wconversion, -fopenmp, -fpreprocessed, -fshort-enums -J Put MODULE files in 'directory' -Waliasing Warn about possible aliasing of dummy arguments [...] ---------------------------------- The same problem with the missing shared options in the output occurs for other languages as well. -- Summary: gcc -v --help returns no options for C, C++ Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: other AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: brooks at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31349
