Symbol stripping

[lto]

Using libtool for several platforms generation is great.
But when I try to compile and link on cygwin using a wrapper of my own 
towards cl and link
it removes the -g flag before calling the wrapper. (I know using gcc and 
ld is better, but our main
application is built on cl for years, and there is no way I can change 
this for now).
I need this flag in order to get debug symbols in the resulting library, 
even if I found a workaround for now.
I hope it can fit with libtool objectives, as a wrapper around any 
building tool.

Best regards,
