The old wsuipa phonetic fonts often don't compile on newer TeX
installations. The wsuipa fonts were superseded by the tipa fonts. The
wsu2tipa program translates a LaTeX file with wsuipa font commands into
a file with tipa font commands.

To compile on Unix:

    flex -B -8 wsu2tipa.l
    gcc -s -Wall -o wsu2tipa lex.yy.c -lfl
    rm lex.yy.c

If you have a C compiler, but no Flex, you can use the pre-flexed file
wsu2tipa.c
