would adding UNSET improve the 'portability' of the scripts?

On my system:

uname -a

Linux fatdog64-bd0 5.19.14 #1 SMP PREEMPT_DYNAMIC Thu Oct 6 02:08:05 AEST 2022 x86_64 Intel(R) Core(TM) i5-5200U CPU @ 2.20GHz GenuineIntel GNU/Linux

I had to run:

unset LIBRARY_PATH CPATH C_INCLUDE_PATH PKG_CONFIG_PATH CPLUS_INCLUDE_PATH INCLUDE

before compliation succeeded.

[Thank you for your work here though- very useful.]
