ENH: Added parsing of gccxml flags into separate arguments for setting the custom command.  This is necessary since the custom command now takes a vector of individual command line options instead of a single string.

Add clause to prevent adding quotes when they're already present, then stuff them
onto all lib paths to prevent forward slashes causing trouble.

with dependencies (other libraries) not linking when required. Dependency checking
required the full path to be supplied to each file when they're not in the current directory
(very tedious). All seems to be working nicely now.

add any extensions - Borland make needs full paths to certain dependencies
otherwise linking doesn't work properly (dependencies aren't checked)

ENH: Removed addition of compiler support directory include option since the find_*_options scripts now include it automatically.

ENH: separate command from its arguments in the custom command.  This allows the generator on windows to change the slashes for just the command

seperated from Convert function

ENH: Generate compile lines for .m, .M, and .mm files (ObjC and ObjC++)

BUG: GCCXML_FLAGS found from find_gcc_options or find_mpro_options should have the trailing newline stripped from the string.
