Re: dlltool -N [PATCH]

[Shaun Jackman <sjackman at gmail dot com>]

I'm using dlltool to create static library wrappers around
pre-existing DLLs (such as coredll.dll and winsock.dll). The dllimport
names, such as malloc, do not have an initial underscore. gcc, otoh,
expects malloc() to be called _malloc. So, -N adds an underscore to
the external symbol, but not the dllimport name.

I'm not familiar with --ext-prefix-alias. I didn't see any reference
to it in dlltool(1). Is it a switch to another program?

Please cc me in your reply. Cheers!
Shaun
