Before sending a bug report, please do two things. First, verify that you have the latest version of gawk. Many bugs (usually subtle ones) are fixed at each release, and if yours is out of date, the problem may already have been solved. Second, please read this man page and the reference manual carefully to be sure that what you think is a bug really is, instead of just a quirk in the language.

gcal—Displays month/year calendar sheets, eternal holiday lists for Julian and Gregorian years, and fixed date warning lists—all in a variety of ways.
SINOPSIS
gcal [[ Option... ][%Date ][@File... ]] [ Command ]
DESCRIPTION
gcal is a program similar the standard calendar programs BSD_'cal' and calendar.
gcal displays Gregorian calendars, Julian calendars (before September 1752).
If gcal is started without any options or commands, a calendar of the current month is displayed.
If the calendar of a definite year is wanted, the year must be fully specified. For example, gcal 94 displays a year calendar of the year 94, not of the year 1994.
If two arguments are given in the command part, the first argument denotes the month and the second argument denotes the year. In case any illegal commands are given running gcal, the program will use internal defaults.
The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September. Ten days following that date were eliminated by the reformation, so the calendar for that month is a bit unusual.
MORE PROGRAM INFORMATION
You get more program information if you start gcal as follows:
gcal -h gcal -? gcal _help resp., gcal -hh gcal -?? gcal _long-help[=ARG]j[=?] gcal _usage[=ARG]j[=?]
A hypertext file gcal.info containing detailed online information should be available, which you can inspect using your GNU Infobrowser.

gcc, g++—GNU project C and C++ Compiler (v2.7)
SINOPSIS
gcc [ option j filename ]. . . g++ [ option j filename ]...
WARNING
The information in this man page is an extract from the full documentation of the GNU C compiler and is limited to the meaning of the options.
This man page is not kept up-to-date except when volunteers want to maintain it. If you find a discrepancy between the man page and the software, please check the info file, which is the authoritative documentation.
If we find that the things in this man page that are out of date cause significant confusion or complaints, we will stop distributing the man page. The alternative, updating the man page when we update the info file, is impossible because the rest of the work of maintaining GNU CC leaves us no time for that. The GNU project regards man pages as obsolete and should not let them take time away from other things.
For complete and current documentation, refer to the info file gcc or the manual Using and Porting GNU CC (for version 2.0). Both are made from the Texinfo source file gcc.texinfo.
DESCRIPTION
The C and C++ compilers are integrated. Both process input files through one or more of four stages: preprocessing, compilation, assembly, and linking. Source filename suffixes identify the source language, but which name you use for the compiler governs default assumptions:
| gcc | Assumes preprocessed (.i) files are C and assumes C-style linking. |
| g++ | Assumes preprocessed (.i) files are C++ and assumes C++-style linking. |
Suffixes of source filenames indicate the language and kind of processing to be done:
| .c | C source; preprocess, compile, assemble |
| .C | C++ source; preprocess, compile, assemble |
| .cc | C++ source; preprocess, compile, assemble |
| .cxx | C++ source; preprocess, compile, assemble |
| .m | Objective-C source; preprocess, compile, assemble |
| .i | Preprocessed C; compile, assemble |
| .ii | Preprocessed C++; compile, assemble |
| .s | Assembler source; assemble |
Page 175
| .S | Assembler source; preprocess, assemble |
| .h | Preprocessor file; not usually named on command line |
Files with other suffixes are passed to the linker. Common cases include
.o Object file .a Archive file
Linking is always the last stage unless you use one of the _c, _S, or _E options to avoid it (or unless compilation errors stop the whole process). For the link stage, all .o files corresponding to source files, _l libraries, unrecognized filenames (including named .o object files, and .a archives) are passed to the linker in command-line order.
OPTIONS
Options must be separate: _dr is quite different from_d _r.
Most _f and _W options have two contrary forms: _fname and _fno-name (or _Wname and _Wno_name). Only the nondefault forms are shown here.
Here is a summary of all the options, grouped by type. Explanations are in the following sections.
