[postgis-devel] flex problems on RHEL 5.1

[Jorgen Austvik - Sun Norway]

Hi, on RHEL 5.1 I see this problem during make:

-------8<---------------8<---------------8<---------------8<--------
flex -Plwg_parse_yy -i -f -o 'lex.yy.c' wktparse.lex
"lex.yy.c", line 1: bad character: #
"lex.yy.c", line 1: unknown error processing section 1
"lex.yy.c", line 2: bad character: #
"lex.yy.c", line 3: bad character: #
"lex.yy.c", line 4: bad character: #
"lex.yy.c", line 5: bad character: #
<snip>
flex: could not create

The following patch seems to fix the issue for me:

I think this is a pretty standard RHEL 5.1:
