cfparse.h defines the YYLTYPE struct in case it has not been defined, and
also declares an extern YYLTYPE cflloc which is used in cflexor.
As cfparse_misc.h defines an extended YYLTYPE, the cflloc instance in
cfparse.c has this extended type, i.e. there is a type mismatch.
Changing the include order in cflexor causes both cflexor.c and
cfparse.c to use the definition from cfparse_misc.h.
This has been uncovered by GCC when using LTO:
---
gcc -flto=8 main.o substit.o cflexor.o cfparse.o -o iverilog
cfparse.h:105:16: warning: type of 'cflloc' does not match original declaration [-Wlto-type-mismatch]
105 | extern YYLTYPE cflloc;
| ^
cfparse.c:1162:9: note: type 'struct cfltype' should match type 'struct YYLTYPE'
1162 | YYLTYPE yylloc
| ^
cfparse.c:1162:9: note: 'cflloc' was previously declared here
cfparse.c:1162:9: note: code may be misoptimized unless '-fno-strict-aliasing' is used
