Bug #1057: ripper does not compile with mingw
http://redmine.ruby-lang.org/issues/show/1057

Author: Charlie Savage
Status: Open, Priority: High
Category: core, Target version: 1.9.1
Reproducible Version: 1.9.1 RC2

Mingw, vista, gcc 3.4.5

When building ruby 1.9.1-rc2:

make[1]: Entering directory `/usr/src/ruby-1.9.1-rc2/ext/ripper'
make[1]: *** No rule to make target `lex.c', needed by `ripper.o'.  Stop.
make[1]: Leaving directory `/usr/src/ruby-1.9.1-rc2/ext/ripper'
make: *** [exts] Error 1

In the makefile:

ripper.o: ripper.c lex.c eventids1.c eventids2.c eventids2table.c \

$ flex --version
flex 2.5.33

$ bison --version
bison (GNU Bison) 2.3

But lex.c is nowhere to be found.  Simply removing it from the makefile fixes the issue.  So:

ripper.o: ripper.c eventids1.c eventids2.c eventids2table.c \

Is this the right solution?
