Subject: Symlink required binutils/BFD headers to local dir
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=512402359d3e75e11c8f057d045b7b97fa070fbc;p=elf2flt.git

Symlink required binutils/BFD headers to local dir

... to minimize the chance of clashes with system headers.

Also, remove the -lcygwin from Makefile.in: this breaks canadian
build on cygwin, as it tries to pass -lcygwin into non-Cygwin host
CC. This chunk pre-dates the addition of -lc into configure.ac and
passing -lc should be sufficient (it works for me).
