The problem seems to be in:
conftest.c -lwinmm  -L/usr/local/lib -lmingw32 -lSDLmain -lSDL -mno-cygwin 
-mwindows >&5
In file included from /usr/local/include/SDL/SDL_main.h:26,
                 from /usr/local/include/SDL/SDL.h:28,
                 from conftest.c:106:
/usr/local/include/SDL/SDL_stdinc.h:165:22: alloca.h: No such file or directory


This probably has to do with how SDL is compiled on your cygwin.
(Was it a cygwin buils or a mingw build (-mno-cygwin))
Cygwin has alloca.h, mingw has not.
