 *
 * DESCRIPTION
 *
 * all options for gcc start with '-' and are for the most part
 * single options (no parameters as separate argument). 
 * There are of course exceptions to this rule, so here is an 
 * exhaustive list of options that do take parameters (potentially)
 * as a separate argument:
 *
 * Compiler:
 * -x language
 * -o filename
 * -aux-info filename
 *
 * Preprocessor:
 * -D name 
 * -U name
 * -I dir
 * -MF file
 * -MT target
 * -MQ target
 * (all -i.* arg)
 * -include file 
 * -imacros file
 * -idirafter dir
 * -iwithprefix dir
 * -iwithprefixbefore dir
 * -isystem dir
 * -A predicate=answer
 *
 * Linking:
 * -l library
 * -Xlinker option
 * -u symbol
 *
 * Misc:
 * -b machine
 * -V version
 * -G num  (see NOTES below)
 *
 * NOTES
 * There is -G option for compatibility with System V that
 * takes no parameters. This makes "-G num" parsing ambiguous.
 * This option is synonymous to -shared, and as such we will
 * not support it for now.
 *
 * Special interest options 
 *
 *      Assembler Option
 *          -Wa,option
 *
 *      Linker Options
 *          object-file-name  -llibrary -nostartfiles  -nodefaultlibs
 *          -nostdlib -s  -static  -static-libgcc  -static-libstdc++
 *          -shared  -shared-libgcc  -symbolic  -Wl,option
 *          -Xlinker option -u symbol --image-base -fuse-ld
 *
 *      Directory Options
 *          -Bprefix  -Idir  -I-  -Ldir  -specs=file
 *
 *      Target Options
 *          -b machine  -V version
 *
 * Please note that the Target Options are relevant to everything:
 *   compiler, linker, assembler, preprocessor.
 *
