Subject: Tweaked Makefile.in so that post-configured Makefile tests for a Cygwin build
X-Git-Url: https://git.wh0rd.org/?a=commitdiff_plain;h=23c458d73c6bccca7102d79e6ec4e31757a09236;p=elf2flt.git

Tweaked Makefile.in so that post-configured Makefile tests for a Cygwin build
environment, and if detected, explicitly adjusts the link order so that
libcygwin links *before* libiberty.a.  This gets around a Cygwin problem with
getopt()'s optind/optarg symbols.  See, for example:

http://sources.redhat.com/ml/cygwin/2004-04/msg01179.html

Also tweaked cygwin-elf.h and elf2flt.c so that Cygwin builds for MicroBlaze
target work as expected.
