[Lynx-dev] Build failures on hppa architectures after update from 2.9.0dev.9 to 2.9.0dev.10

[Axel Beckert]

Hi,

on Debian we noticed build failures of Lynx 2.9.0dev.10 on the (IIRC
kinda vintage) hppa architecture (see
https://www.debian.org/ports/hppa/ + https://parisc.wiki.kernel.org/)
where Lynx 2.9.0dev.9 still build fine:

https://buildd.debian.org/status/logs.php?pkg=lynx&arch=hppa

The problem seems to be reproducible, at least two build runs of Lynx
2.9.0dev.10 failed so far.

The relevant compile error seems to be this:

gcc -DHAVE_CONFIG_H  -I../../.. -I../../../src -I../../.. -I../../../src  
-I../../../WWW/Library/Implementation  -Wdate-time -D_FORTIFY_SOURCE=2 
-DNO_BUILDSTAMP -D_FILE_OFFSET_BITS=64   -DLINUX -D_DEFAULT_SOURCE 
-D_XOPEN_SOURCE=600 -D_GNU_SOURCE -D_XOPEN_SOURCE_EXTENDED -g -O2 
-ffile-prefix-map=/<<PKGBUILDDIR>>=. -Wformat -Wall -Werror=format-security    
-I../../../WWW/Library/Implementation/ -DACCESS_AUTH -c 
../../../WWW/Library/Implementation/HTMLGen.c

I suspect that some of the fixes for the fuzzer-found issues are not
compatible with some rough edges of that architecture.

                Kind regards, Axel
