Mattias,

Find Declaration shows two entries in file osutilsh.inc, lines 25 and 26:
Function GetEnvironmentVariable(Const EnvVar : AnsiString) : AnsiString;
Function GetEnvironmentVariable(Const EnvVar : UnicodeString) : 
UnicodeString;

But Code Completion offers three functions named GetEnvironmentVariable:
The Ansistring function and the Unicode String function above plus
"GetEnvironmentVariable(lpName: LPCSTR; lpBuffer: LPSTR; nSize: DWORD): 
DWORD".

Seems, Lazarus tries to use only the latter.

No, I don't have another GetEnvironmentVariable.

You can reproduce this easily:
Put a TButton Button1 on a form.
In the OnClick Event for this button write "Button1.Caption := 
GetEnvironmentVariable ('computername');"

Version Info (Thank you for this hint):
Lazarus 1.8.0RC1 r54919 FPC 3.0.2 x86_64-win64-win32/win64
