[Coin-ipopt] build error

Hi All,

I've "successfully" compiled IPOPT on Win32 using native MinGW and MSYS. A 
few points:

  - uppercase vs. lowercase shouldn't matter to windows (unless you're 
wanting to distinguish makefile from Makefile, in which case you're screwed 
- but I don't think that's an issue here).

  - When I was executing ./configure (under MSYS command window), the 
script might halt part-way, having difficulties creating links to working 
directory copies of files it had already duplicated (i.e., from 
distribution directory, to parallel working directory).  IIRC, this was for 
one of the OTHERS/ modules (can't remember which).  Maybe it was for ASL. 
I commented out the line in the configure file that was attempting the 
failed linking, reran configure, and things were fine.

  - I know I manually ran the ASL makefile directly (after configure 
created it). I edited it to redefine CFLAGS as:
   CFLAGS = -O3 -DNON_STDIO -DNO_RUSAGE -funroll-loops
There *may* be a separate issue about whether this should be -O2 vs. -O3.
