Recursive update control

GmkPack can either compile and re-compile all that is in the pack, or compile only what is out of date and stop early when the compilation fails on a file.

In main packs the default behavior is to compile or recompile everything ; should the compilation fail on some files, then GmkPack will report about them only at the very end of the compilation :

# Do you want to enable the recursive update control ? (yes/no) ?
# --------------------------------------------------
export ICS_RECURSIVE_UPDATE=no

In ordinary packs the default behavior is to compile only what is out of date and stop early when the compilation fails on a file :

# Do you want to enable the recursive update control ? (yes/no) ?
# --------------------------------------------------
export ICS_RECURSIVE_UPDATE=yes

Notice :

• Using the recursive update control is supposed to be faster, unless the content of the pack is huge (then you might spend more time checking files and dates than compiling).
• If the recursive update control is activated and a file (module or header) is out of date, then its dependencies will automatically become out of date (GmkPack will remove the depending object files).
