/*
* MinGW wrapper: makes gcc behave like MinGW.

*
* 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.
*
