[Flex-help] Filter for lineno

[MockF M. <moc...@ya...>]

Hi,



I had difficulty in building flex in Windows because there is no regex.h in MSVC. When I check the source code I find that only filter_fix_linedirs is using regex.

It seems one purpose is to adjust all "#line num xxx.l" but not "#line num xxx.c" where xxx.c is the generated file name. When there is any compiling error only line number for xxx.l is reported. Is where lineno for xxx.c can be reported? If not why don't we ignore it or remove it?

Thanks
