which raises the question of what's in strings.h
According to
https://support.hpe.com/hpesc/public/docDisplay?docId=emr_na-c02128447
HPE
C/C++ Programmer's Guide for NonStopSystems
it says it's compliant:
Writing programs to international standards enables you to move them
between different hardware andsoftware environments with little effort.
Write your C programs to comply with the ISO/ANSI C standard:ISO/IEC
9899:1990, Programming Languages–C plus features from 1999 update to
this standard (see c99 Selected Features (C99LITE) on page 598 for
TNS/E programs on H06.21 and later H-series RVUsor for J06.10 and later
J-series RVUs, see c99 Full Support on page 602 for TNS/E and TNS/X
native applications for H06.21 and later H-series RVUs, J06.10 and later
J-series RVUs, and L-series RVUs,and see c11 Support for TNS/X
Compilers conform to the 2011 ANSI C Standard starting from L16.0548
Writing Portable Programs RVU. c11 supports compilation of C and C++
programs). For a complete description of ANSI C, see ANSI X3.159
however, I'm reminded that strings.h is only standardized to include
the legacy BSD stuff - described here:
https://pubs.opengroup.org/onlinepubs/009695399/basedefs/strings.h.html
while picsmap is using several functions from the modern version string.h:
https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/string.h.html
strchr
strcmp
strcpy
strlen
strncmp
strstr
(strstr vs index used to be something I took into account in ports)
