>Description:
yacc-generated output holds a code sequence
extern char getenv();
xxx = getenv("XXX");
which makes C++ compilers like g++ complain/fail because of
prototype mismatch.

yacc/skeleton.c
No good idea, since most solutions depend on previous #include statements,
like surround offending declaration with __BEGIN_DECLS/__BEGIN_DECLS
Maybe:
#if defined(__cplusplus)
extern "C" {
#endif
extern char getenv();
#if defined(__cplusplus)
};
#endif
